In the purpose of this method, in the device and its power-saving method, the control (four) and the power supply have power-saving effects. In order to achieve the above object, according to one aspect of the present invention, a power saving control device is provided for saving power consumption of an electromagnetic interference waver of a power supply, including: A first rectifier circuit and a switch circuit. The first rectifier circuit can rectify an AC power source and output a DC power source.

In order to solve the above technical problem, according to another aspect of the present invention, a power supply device includes: an electromagnetic interference filter, a power saving control device, and a second rectifier circuit. The electromagnetic interference filter is coupled between the power saving control device and the second rectifier circuit. The power saving control device has a first rectifier circuit and a switching circuit. The first rectifying circuit can rectify the -j current source to output a DC power source; the switching circuit can control one of the down power source and the DC power source to be input to the electromagnetic interference filter. In order to solve the above technical problem, according to still another aspect of the present invention, the power saving method of the power supply is suitable for saving the power supply, the electromagnetic interference filter, and the power consumption of the wave device, which is supplied by the power supply. In the state, the AC power is input to the power supply as the loader supplied by the source and the source supply 11, and the DC power is input to the electromagnetic interference filter.

M t (four) interference chopper passer set in the f source supply. The previous power loss is mainly caused by == and the second electric slant in the power supply n. The f = 'The new NB invention is mainly wireless, to greatly reduce the capacitance. The capacitive reactance of the capacitor is close to the power consumption of the disturbance, and the power supply has the effect of saving power, and the image of the system is the first embodiment of the present invention. Electricity 2:: is the block diagram. The power supply 1 of the second figure includes - 14, ^ by two sets, an electromagnetic interference waver 12 and a second rectifier circuit of the packet control device 10 coupled to the electromagnetic interference filter 12, * Γ〇: between the ends of the 'electromagnetic interference chopper: between the power-saving control two direct current circuit 14' the output of the second rectifier circuit 14 is, and can be loaded with 9 power. When the power supply 1 supplies power to the load 9, e π ignites the working state of the load 9, and controls the power supply 1 = in the normal power supply mode or the power saving mode. In this implementation, the bias is implemented. When the working state of the field load 9 is the normal mode, then the power supply 1 is in the normal power supply mode, and when the working state of the load 9 is the power saving 201104406, the power supply 1 is relatively operated in the power saving mode. . ^ The electromagnetic interference filter 12 and the second rectification circuit in Hi are conventionally known, and will not be described in detail herein. :,1. Then, it is used to control the power supply α to operate in the electric power supply mode, as shown in the second figure, the power saving control; set: VL includes a first-rectifying circuit 101 and a switching circuit 103, wherein: the rectifier circuit 1G1 is used for the transmission In the power supply 1 - AC power supply into the rectification and output - DC power supply 'switching circuit 1G3 is to control the electromagnetic dry mountain; consider the wave $ 12 to receive the AC power or connect (four) the __ rectifier circuit such as the straight ΛΗ_Power' and the switching circuit 1〇3 is exemplified in parallel with the first rectifier circuit 1 〇1, but it is not limited thereto, and may be other connection relationships, such as a series connection. The operation principle of the power-saving control device 10 is further explained. The eye-opening circuit 103 in the power-saving control device 10 is exemplified by a -switching switch. The function of the switch can be used to control the input of electromagnetic interference. The signal transmitted by the transmission path of the filter 2 is an AC power source or a DC power source. For example, when the switch is turned on (turn 〇η), the AC power source is directly transmitted to the EMI filter 12 through the switch; When the switch is turned off, the DC power output from the first rectifier circuit 1〇1 is output to the electromagnetic interference filter 12. The conduction or the interception of the switch can be determined according to the working state of the load 9. For example, when the load 9 is in the positive suspension mode, the switch is switched to the on position, and when the load 9 is in the power saving mode, the switch is switched to the wearing position. Therefore, when the electromagnetic interference filter 12 receives the AC power input, The power consumption of the inner 4 is generated by the capacitive reactance of the χ/γ capacitor and its equivalent series resistance (ESR), coil, line loss, etc. However, when the electromagnetic interference filter 12 201104406 When receiving the ^: stream power input, since the 电磁/γ 电 谷 谷 谷 电磁 γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容 电容The power consumption of the electromagnetic interference filter 12 saves only about $ lap and the power consumption of the line loss. Therefore, the power consumption generated by the electromagnetic interference filter 12 when receiving the DC power supply will be higher than the power generated when the AC power supply is received. The consumption is relatively small. That is to say, the power supply device 达到 under the control of the power-saving control device 1〇, the power supply can be achieved when the electromagnetic interference filter 12 receives the DC power supply. The power supply can still be continued to be used by the load 9. If the packet source supply 1 is to be restored to the normal power supply, the switch circuit 103 of the power-saving control device 10 can be used to cut the conduction position. s凊 See the third figure. The figure is a block diagram of a power supply device according to a second embodiment of the present invention. The power supply unit 1a of the third figure includes a power-saving control device 10a, an electromagnetic interference filter 12, and a second Rectification The circuit 14 and the technical characteristics of the power supply la φ are the same as the first one except that the connection between the first rectifier circuit ι〇ι& and the switch circuit 1〇3a in the power-saving control device 1A is different. The second figure is the same. In the power-saving control device 10a of this embodiment, the switch circuit 103a is a switch, and the switch 4 is switched to the position of point A or point B to determine that the electromagnetic interference filter 12 is To receive an AC signal from the transmission path of point A or receive a DC signal from position B. For example, when load 9 is in normal mode, the switch is switched to a point position and the parent current power supply is directly input to the electromagnetic interference filter. 1 2, and when the load 9 is in the power saving mode, when the switch is switched to the B point position, the DC power output of the first rectifier circuit l〇la is output to the electromagnetic interference filter Η, where the first rectification The circuit l〇la is described by a half-wave rectification circuit. 201104406, and then refer to the fourth figure', which is a block diagram of the power supply of the third embodiment of the present invention. The power supply device 1b of the fourth figure includes a power saving control device 1Gb, an electromagnetic dry (four) wave device 12, and a second rectifying electric power: except the first rectifying circuit 101b is a full wave rectifying circuit (or a bridge type whole machine, In addition to the example, the technical characteristics of the other power supply lb are the same as those in the third figure. Here, the switch circuit 1 also determines the power interference filter, and the wave filter 12 is to be transmitted from point A. The path receives the AC signal or receives a DC signal from the b point. As for the actual operation mode of the aforementioned switching circuit, it can be performed by an automatic switching method. For example, the switching circuit can control the switching state of the switching switch according to a received control signal, and the switching state can be the switching according to the second figure, the fourth (four) is turned on or off, or the third and fourth figures are as follows. Switch to position A or point B. The control signal can be the signal that the load enters into the power saving mode. Therefore, for the switch circuit, it is possible to know the remaining state according to the presence or absence of the (four) age, and the system receives the control signal to know that the load has been entered into the ship to make the switch clear, so that the switch circuit receives When controlling the signal, it provides a transmission path connection of the output DC power supply, the electromagnetic dry input terminal, or the transmission path of the supply-output AC power supply is connected to the input end of the electromagnetic interference filter when the (5)_胄路 does not receive the control signal. .

The power supply of the fifth figure includes a power-saving control device l〇c' - an electromagnetic interference chopper 12 and a second rectification circuit 14 in which the power-saving control device is placed in the _ _ _ _ _ _ _ _ _ _ _ _ _ _ Between the input terminals, the electromagnetic interference filter 12 is coupled between the power-saving control device i〇c and the second rectifier circuit 14, and the output of the second rectifier circuit 14 is 201104406 to directly supply power to the load.
