The present invention relates to a power-saving power supply device for integrated power management, and more particularly, to effectively cut off standby power to obtain a power saving effect and a fire prevention effect, and to minimize power consumption by minimizing unnecessary power generation during use. The present invention relates to a power-saving power supply unit for integrated power management to maximize the voltage and stabilize the voltage supplied to the equipment used.

In recent years, the rapidly changing information and communication technology and the communication speed of information and communication devices is increasing rapidly for a more convenient life. As a result, households are becoming more dependent on electricity, which in turn leads to higher power output, which in turn leads to a significant increase in energy resource imports. However, the energy saving movement and numerous energy saving policies are being implemented in the high oil price era, but the effectiveness is not great without the voluntary participation of the people.

As part of the energy saving policy, passively cut off power strips are commonly used to cut off standby power in ordinary homes or offices. However, such a passive cut-out power strip has a disadvantage that it is cumbersome and difficult to cut off power after use of an office equipment because it is installed at a corner of a desk or a floor.

Recently, the sale of power-saving automatic power circuit breakers has been made, and the representative one is "HiSaver / PC Auto Tap."

Such a power-saving automatic power circuit breaker can have many advantages in reducing standby power, but can not cut off unnecessary power generated during actual use, and thus has a limitation in its function.

Here, UPS refers to an uninterruptible power supply that provides high quality stable AC power by overcoming power failures that may occur in commercial power, and DSP / DIP FREE refers to an instantaneous power compensation device and a surge protector.

However, because the circuit is complicated and expensive in terms of price, the reality is that the consumer and the equipment used in the general home or office equipment are ignored.

In addition, due to excessive maintenance and installation costs in the industrial field, it is only used to some extent by large companies that deal with expensive semiconductor and liquid crystal display (LCD) equipment. The situation is suffering a lot due to the installation cost and maintenance.

Nobody can predict when and when these momentary interruptions and voltage dips will occur. Not only large businesses, but also small and medium businesses, general offices, and individuals must protect information from accidents.

Meanwhile, FIG. 3 to FIG. 10 are detailed circuit diagrams of respective functional units constituting the power saving type power supply device 100 for integrated power management.

First, a detailed circuit diagram of the EMI filter unit 102 is shown in FIG.

Referring to FIG. 3, the EMI filter 102 is a region directly connected to the input terminal AC, and is composed of two filters. Therefore, a common mode and a normal mode, that is, a function of suppressing a high frequency noise generated from the outside and a high frequency noise component generated from the inside are performed.

Is output via At this time, the current flowing through R1 is sensed by U1 to minimize the phase difference between the input voltage and the current (to match the phase), and boost the input full-wave rectified voltage by a predetermined voltage or more to generate a stable DC power supply. Thus, by matching the phase of the voltage and the current, it is possible to suppress the harmonics generated unnecessarily, thereby minimizing the input power by suppressing the reactive power.

5 is a detailed circuit diagram of the charging voltage and current control unit 106, the emergency energy charging unit 108 and the emergency energy discharge connection unit 110 in sequence.

Referring to FIG. 5, the charging voltage and current control unit 106 uses the stable DC power rectified by the AC-DC rectifying unit (PFC) 104 by using R2 and R12, and C3 and C38 of the emergency energy charging unit 108. And to charge the C42 and limit inrush current generated during the charging process to prevent tripping of circuit breakers in homes and businesses and to minimize distortion of input power.

In addition, the emergency energy charging unit 108 charges the voltage supplied to the charging voltage and the current control unit 106 to minimize the distortion of the output voltage caused by the instantaneous power interruption, the instantaneous voltage drop and the increase of the power consumption, and for a predetermined time. It functions as an energy storage device capable of supplying energy to the load.

In addition, the emergency energy discharge connection unit 110 prevents the discharge of the emergency energy charging unit 108 at a normal power input, and functions as a connection circuit device for discharging stored energy to the load side at abnormal power input.

Therefore, when the voltage output to the load is lowered by 0.7 V or more than the voltages of C3, C38, and C42 of the emergency energy charging unit 108 due to a change in input power (AC power) or an instantaneous power interruption, the charged voltage is transferred through D1. Power up the load quickly. When the input power is normally input, since the output voltage rises faster than the voltage of the emergency energy charging unit 108, the power supplied to the load side through the D1 is cut off by the D1 to charge the energy normally.

Referring to FIG. 6, the power supplied from the AC-DC rectifier (PFC) 104 charges C44 through R34 and D14. At this time, the inrush current generated by the C44 is suppressed by R34, and the voltage charged in the C44 cannot be discharged by the D14 even if the input voltage drops sharply, thereby stably supplying power to the auxiliary power supply 112. Being able to supply, it functions as a power supply for stably controlling the control microcontroller 116 and the internal elements.

The auxiliary power supply 112 is configured as a buck converter to convert the input voltage of DC 365 ~ 380V to DC 15V used by the control elements.

And, if the input voltage falls below 100V, power conversion is blocked by UVP (Under Voltage Protection) of the auxiliary power supply 112, thereby completely blocking the power supplied to the control elements to prevent damage to the devices and unnecessary malfunction.

At this time, the D6 is provided to prevent the overcurrent flow due to the abnormality of the equipment connected to the output to be damaged by a signal above the input limit voltage of the control microcontroller 116. When the input voltage (current amount) is 0.4V or more higher than the power supply voltage (DC 5V) of the control microcontroller 116, the D6 blocks the power supply voltage + 0.4V or more.

In addition, when the fan is driven, the normal operating state is sensed using CHECK_FAN_PORT, the equipment is prevented from being damaged due to overheating, and the presence or absence of a user is determined using SEN / SW_INPUT PORT to select the power of the auxiliary power supply 112, and AC Control of the DC rectifier (PFC) 104 can minimize the current consumption in the standby state.

And, by using the current conversion value input through CURRENT PORT, the power can be cut off and supplied, and an alarm can be generated, and after the user is detected, it can automatically switch from the standby state to the normal driving state.

9 is a detailed circuit diagram of the sensor-linked power-on switch 118 is shown.

Referring to FIG. 9, the sensor SEN1 detects a signal for the presence or absence of a user by using an infrared sensor and amplifies the detected small signal to a predetermined voltage or more through U8D / B / D. The ring amplified signal is converted to a predetermined time period or more through peak detectors D2, C34, and R26, and transmitted to the control microcontroller 116.

10 is a detailed circuit diagram of the two-channel power cut-off switch 120.

It is operated by the control microcontroller 116, it is characterized by consisting of relays RL1 and RL2 that can be turned on or off (On / Off) of the output of the external outlet and the power converter 122. . In order to protect the contacts of the RL1 and RL2 from sparks generated when the relays RL1 and RL2 are driven, the RL1 and RL2 may be provided with capacitors C19 and C33 that absorb spark noise, respectively, to further extend the lifespan.

In addition, it is possible to control the voltage supplied to the external device through the voltage supplied to the power converter 122 and the output outlet, respectively, so that if the appropriate control and the power saving state signal is received from the control circuit of the main equipment, the power saving is more effectively induced. can do.

Hereinafter, with reference to the drawings, the operation of the integrated power management power-saving power supply device 100 according to the present invention will be described collectively as follows.

The power input through the input terminal is input to the AC-DC rectifier (PFC) 104 through the EMI filter unit, the input power is converted to DC 365 ~ 380V in the AC-DC rectifier (PFC) 104. The power converted through the AC-DC rectifier (PFC) 104 is output through a switch 120 for power cutoff of two channels, and the power of the converted DC 365 to 380V is emergency energy through R1 and R12. The capacitors C3, C38 and C42 of the charging unit 108 are charged.

In this case, the in-rush-current generated in the process of charging power to the capacitor of the emergency energy charging unit 108 is limited by R1 and R12, thereby causing damage to the inside of the device, the circuit breaker installed in homes and businesses. Distortion of input power can be minimized by preventing trips and limiting inrush current.

At this time, when the input power is normally introduced, since the output voltage rises faster than the voltage of the emergency energy charging unit 108, the power supplied to the load side through D1 is cut off by D1, and charges energy normally.

However, when the power consumption consumed by the load is increased or the output voltage is lowered by 0.7 V or more than the voltage of the emergency energy charging unit 108 due to the distortion and instantaneous power failure of the input voltage, the charged voltage is quickly supplied to the load through D1. The power supply is stabilized by minimizing the power supply ripple of the output power supply. Since such output power is appropriately limited by the switch for turning off the power, unnecessary power consumption (standby power) can be suppressed.

In addition, the AC-DC rectifier (PFC) 104 converts the input AC power supply to DC 365-380V, and minimizes phase difference between voltage and current, thereby minimizing unnecessary power distortion and unnecessary reactive power. By suppressing, power generation (apparent power) generated in actual power plant is reduced, and economic loss is reduced by reducing power system loss caused by reactive power, and electricity charges that are set in general households (when power factor is set at 90% standard) It can save about 30%.

In addition, by supplying a stable DC power supply to the equipment used to extend the life of office equipment using the SMPS-type power supply to reduce unnecessary waste of repair and replacement costs.

In addition, by using the control microcontroller 116 for proper control of the power cut-off switch 120, it is possible to prevent damage to the device and increase energy saving through accurate and safe control.

The control microcontroller 116 receives the power supply (DC 15V) from the auxiliary power supply 112 and changes to the required power supply (DC 5V), the amount of current input from the current sensing unit 114 and the power sensor interlocking power on The signal input from the switch 118 controls the on / off of the switch 120 and the AC-DC rectifier (PFC) 104 for the power cut through the entire system control algorithm.

The pushbutton switch of the sensor-linked power-on switch 118 is a device that interlocks with the sensor in parallel and operates to automatically and manually apply power.

And, according to the state of the device to inform the user of the state using the output display (LED). Therefore, by monitoring the output current at all times, it is possible to prevent the secondary damage of the user equipment by blocking the power switch by detecting the overcurrent generated momentarily.

In addition, the voltage input to the auxiliary power supply 112 uses the power charged by the emergency energy charging unit 108 and the AC-DC rectifying unit (PFC) 104, and the emergency energy charging voltage is increased due to a long power failure. If it falls below a certain voltage (DC 100V), the power output to the control microcontroller will be cut off to prevent malfunction of the equipment.

The DC power controlled by the AC-DC rectifier (PFC) 104 is supplied to and operated by an SMPS type power converter 122, and the external power control device for power saving type integrated power management according to the present invention ( 100 may be directly input to control the driving command of the power converter 122. In addition, by supplying the driving voltage of the power converter 122 in the integrated power management power-saving power supply device 100 does not require a separate auxiliary power supply, it is possible to minimize the standby power. Then, the converted power can be supplied to the power of the devices connected to the outside through the external output controller 121.

As described above, in the present invention, the EMI filter unit 102, the AC-DC rectifying unit (PFC) 104, the charging voltage and current control unit 106, the emergency energy charging unit 108, the emergency energy discharge connection unit 110, Auxiliary power supply 112, current sensing unit 114, control microcontroller 116, detection sensor interlocking power on switch 118, two-channel power switch 120, power conversion unit 122, conversion By connecting the power-saving power supply unit 100 for power management, which is composed of the power external output controller 121, to a power supply such as an SMPS, minimizing reactive power generated when the power is used, to reduce unnecessary power waste and at the time of power-off ( In the standby state, unnecessary standby power consumption can be cut off by the whole system, and the power failure can be compensated for a certain time even in case of power failure and voltage drop occurring in the power system. In addition, the integrated power management power-saving power supply device 100 according to the present invention can be more reasonably energy-saving by embedding an artificial power saving function using an automatic control system as well as damage caused by momentary power failure and voltage drop. To lose.

In addition, the integrated power management power-saving power supply device 100 according to the present invention is configured alone and can be configured in the product without being installed outside, it is expected to be able to greatly help in cost reduction and function enhancement. In fact, by embedding a high-efficiency power converter, the harmonics generated during use can be restrained to the maximum, reducing the harmonic content (THD) to less than 5%, which can reduce the apparent power that needs to be generated for the equipment in the actual power plant by more than 30%. By using microcontroller and various sensors, unnecessary power consumption can be cut off to maximize energy saving. In addition, since the power source of the electronic products can be cut off at the source, it is possible to minimize the damage caused by fire accidents and electric shock accidents.

For example, the above-described effect can be obtained by applying the power supply method by the power saving type power supply for integrated power management according to the present invention to a computer power or a power for an LCD TV.

In addition, FIG. 12 shows a basic configuration example of a computer that can control power of peripheral devices and automatically cut off standby power by using the power saving power supply unit for power management illustrated in FIG. 1.

By incorporating the power-saving power supply for the integrated power management, it is possible to collectively control the power of the devices connected to the peripheral. In this way, by controlling the power of the devices as a whole, it is possible to determine the use status of the devices, and automatically shut off the power of the entire system when not in use, so that the standby power of the entire system can be operated at a level of 0.5W The built-in improvement circuit minimizes the reactive power generated when the power supply is used to reduce unnecessary power waste. In addition, it is easy to store energy by converting to DC by using AC power supply, and can protect the equipment from instantaneous power failure and voltage drop (within 1 second) from natural disasters and power accidents occurring in power line system.
