Description

[0001] The present invention relates to an inverter control switch for a portable and mobile commercial power supply,

The present invention relates to a switch for controlling an inverter of a portable and mobile commercial power supply, and more particularly, to a switch for turning on an inverter when a plug of an external power supply to be used is plugged into a portable power supply, It is also possible to improve the long-term durability of the inverter, to reduce the manufacturing cost by not installing the inverter switch separately, and to reduce the lifespan of portable and mobile commercial power supply devices And a switch for inverter control of a portable commercial power supply.

In general, electric appliances that require power supply can be conveniently used at any time by plugging commercial electric power provided by KEPCO into an outlet provided in a home or office. However, in a place where commercial electricity is not provided, The battery may be powered by an integrated or detached battery.

In addition, since the battery can not be used for a long time due to the limitation of its own capacity, AC power is supplied to an external device through a DC and an inverter when an external device (load) requiring power is connected to allow an external device to be used for a long time Portable and mobile commercial power supplies have been developed.

Such portable and mobile commercial power supply devices may be charged through commercial electric power provided by KEPCO, but they may be charged using energy generated from sunlight, water, wind, and the like.

In addition, although the above-mentioned spread of portable and mobile type commercial power supply devices can not be a direct cause, recently, the interest to outdoor activities has increased and the population to enjoy activities such as camping, fishing and vacation has increased significantly According to the National Statistical Office, the camping population, which was 600,000 people in 2010, has surpassed 1.3 million last year.

In addition, as the culture of camping, etc. is changed into a family unit, not only men in their 40s and 50s, but also young men, women and children in their 20s and 30s are consuming supplies. As the culture of outdoor activities changes, And the use of IT products is gradually increasing, which is not unrelated to the spread of portable and mobile commercial power supplies.

However, although the portable and mobile type commercial power supply apparatuses are larger in capacity than the on-board type batteries, the charging capacity is limited, the power is consumed due to the use of the external power supply apparatus and it is inevitably discharged. In addition, in the case of a commercial power supply using renewable energy such as solar power, wind power, fuel cell, etc., an inverter for commercial power supply is adopted. However, the problem that the efficiency of utilization is lowered due to the standby power of the inverter there was.

However, even if the discharge is caused by the use of the external power supply device, even if it is not used, there is a serious problem that the discharge is reduced from several watts to several tens of watts due to standby power.

The reason for this is that the switch for turning the inverter on and off, which is mounted so as to be able to use the charged direct current in the portable and mobile commercial power supply unit by connecting it to the external commercial power supply based unit, , Since the on-off switch is not applied from the beginning to compete with the market price, the portable battery is continuously discharged due to standby power, and the use efficiency of the renewable energy source is lowered.

In general, an inverter is a device for converting a DC power source to an AC power source. Normally, the DC power source obtains a frequency of a step wave (square wave) type and a required voltage, and converts it into a stable sinusoidal wave It is possible to output a commercial power source having a good waveform.

Generally, inverters are widely used in equipment such as photovoltaic, wind power, fuel cell, etc. in which the form of power generation is output to DC. In recent years, it has been applied to charging and discharging devices such as ESS, So that power can be obtained.

However, in the case of the inverter, since the commercial power is always in standby state for the immediate output even if the user does not use it, the circuit design stands by at a high voltage just before the commercial power supply. This causes battery discharge and power dissipation.

The inverter of portable and mobile type commercial power supply supplied to the market is also designed to have standby power. When connecting the portable and mobile type commercial power supply to the external device, a power switch that normally operates the entire device and a direct current And the external device is operated when the plug of the external device is connected to the outlet.

In this case, when the external power supply is not used, the plug must be disconnected from the portable and mobile commercial power supply, and the on / off switch of the inverter must also be turned off. By turning on / off the switch by turning off / And the battery inside the portable commercial power supply device is discharged and lost, and the efficiency of use of the new and renewable energy generating device is lowered.

In other words, the cause of the discharge of portable and mobile type commercial power supply apparatus can be classified into a general discharge by use and a discharge which is discharged by not turning off the inverter switch.

Unfortunately, most portable and mobile commercial power supplies currently on the market are equipped with only a power switch or a power switch and an inverter on-off switch, There is a problem that the internal battery is discharged or lost below the reference voltage to become permanently disabled or discharged to the reference voltage and the battery can not be discharged any more.

On the other hand, there is an attempt to electronically detect whether or not the user uses the commercial power supply. The electronic circuit installed in the commercial power supply supplies micro currents to both ends of the socket at equal intervals to measure the contact and internal resistance of the plug However, if the time setting of the equal interval is short, the on time of the inverter becomes longer and the standby power reduction efficiency becomes lower. If the time setting of the equal angle is long, the inverter turns off time The standby power is reduced, but even after the user plugs in the plug, it is possible to finally output the commercial power only after the set time has elapsed and after the re-monitoring three currents are sent to determine whether the plug is inserted. Therefore, there is little effect of reducing standby power consumption, or even if the user plugs in the plug, the inverter may not operate immediately and cause confusion.

Portable and mobile commercial power supply units are disclosed in Patent Registration No. 10-1320295 (entitled Portable and Mobile Commercial Power Supply Unit), to which the present applicant is a registrant, which is also equipped with a power switch and an inverter switch respectively There are currently no devices that can control this at a moment.

Therefore, in order to solve the above-mentioned problem, according to the present invention, the inverter is immediately turned on only when the plug of the external power source device to be used is plugged into the portable and mobile commercial power source device, And to provide a switch for controlling an inverter of a portable and mobile commercial power supply apparatus capable of reducing the heat generation at the same time as the portable power supply apparatus and saving the service life of the portable and mobile type commercial power supply apparatus due to the interruption of standby power.

It is a further object of the present invention to provide a method for manufacturing a mobile and portable commercial power supply device by not installing a separate inverter switch.

In order to achieve the above object, the inverter control switch of the portable and mobile commercial power supply apparatus of the present invention will be described below.
A mobile and portable commercial power supply having inverters,
