Problems solved by technology

[0003] In the prior art of the zero-power standby circuit currently proposed, there is a method for realizing zero-power consumption of home appliances. Although the method apparently realizes AC zero-power consumption in standby, it consumes the chemical energy of the battery during standby. , and the battery needs to be charged during work, which increases the power consumption during work, and the life of the whole machine is affected by the life of the battery, and the failed battery will pollute the environment more
In another existing technology of zero-power standby for household appliances powered by supercapacitors, although it does not use batteries, it cannot be completely started by remote control. After the electric energy of the capacitor is exhausted, it needs to be started manually, which is not true standby

Embodiment 1

[0014] Embodiment 1, please also refer to Figure 1A and Figure 1B It is a schematic diagram of a zero-power standby circuit according to Embodiment 1 of the present invention. The zero-power standby circuit according to Embodiment 1 of the present invention includes a first power-on and power-off execution unit 10 and a standby control unit 20 . Such as Figure 1A and Figure 1B shown, where Figure 1A circuit with Figure 1B The circuit of is connected to ND4 through nodes ND1, ND2, ND3.

[0015] Such as Figure 1A As shown, the initial power-on and power-off execution unit 10 includes a rectifier diode VD800, a current limiting resistor R801, a current limiting resistor R802, a current limiting resistor R803, a filter capacitor C800, a relay coil JK800A, a transistor switch V801, a starting capacitor C801, a pull-down Resistor R809 and Zener diode VZ800. Specifically, the first end of the whole machine fuse F800 is connected to the power supply, the second end of the w...

Embodiment 2

[0026] Example 2, please refer to Figure 2A and Figure 2B is a schematic diagram of a zero-power standby circuit according to Embodiment 2 of the present invention, wherein Figure 2A circuit with Figure 2B The circuit of is connected to ND4 through nodes ND1, ND2, ND3. Such as Figure 2A and Figure 2B As shown, the connection relationship of some circuit components is the same as that in Embodiment 1, and will not be described in detail below. The difference between the second embodiment and the first embodiment lies in that the photoelectric coupler PHO801 controlled by a silicon controlled rectifier is used instead in the execution unit 12 of the first power-on and power-off in the second embodiment. Since this type of photocoupler PHO801 can only be turned off by current zero-crossing or anti-correlation, a diode VD804 and a capacitor C804 are added.

[0027] Such as Figure 2A and Figure 2B As shown, when the single-chip microcomputer IC801 sends a power-on s...

Embodiment 3

[0028] Embodiment 3, please refer to Figure 3A and Figure 3B is a schematic diagram of a zero-power standby circuit in Embodiment 3 of the present invention, wherein Figure 3A circuit with Figure 3B The circuit of is connected to ND4 through nodes ND1, ND2, ND3. Embodiment 3 uses optocoupler PHO801 and silicon controlled rectifier TR800 to replace the coil and mechanical contacts of relay JK801 in Embodiment 2, and silicon controlled rectifier TR800 is a bidirectional thyristor.

[0029] Such as Figure 3A As shown, when the photodiode on the primary side of the photocoupler PHO801 is turned on, the thyristor on the secondary side is turned on and triggers the silicon-controlled rectifier TR800 to turn on, and it is naturally turned off when it crosses zero. The negative half cycle is the same, when the photocoupler When the primary side diode of the device PHO801 is cut off, the silicon controlled rectifier TR800 is cut off, the AC power is blocked, and zero standby i...

Abstract

A zero-power-consumption standby circuit is arranged between an alternating-current power supply and a load circuit. The zero-power-consumption standby circuit comprises a first-starting and starting and closedown executing unit (10), a photoelectric coupler (PH0800) and a standby control unit (20). The first-starting and starting and closedown executing unit (10) is provided with a relay (JK800A, JK800B, JK800C) and the relay (JK800A, JK800B, JK800C) is actuated by receiving power of the alternating-current power supply, and accordingly conducts an electric loop between the alternating-current power supply and the load circuit. The photoelectric coupler (PH0800) is provided with a primary side and an auxiliary side, wherein the primary side is connected to the first-starting and starting and closedown executing unit (10). The standby control unit (20) connected to the auxiliary side of the photoelectric coupler(PH0800) receives first remote-control signals and turns off the photoelectric coupler (PH0800) to release the relay (JK800A, JK800B, JK800C), and disconnects the electric loop between the alternating-current power supply and the load circuit.

Description

technical field [0001] The invention relates to the technical field of a standby circuit, in particular to a standby circuit which has no power loss and does not use a mechanical power switch during standby. Background technique [0002] As the global climate is getting warmer, energy conservation and emission reduction has become the top priority of the governments of various countries, especially the home appliance industry, which is closely related to daily life, has been pushed to the forefront. In the European and American markets, low power consumption, together with safety regulations and EMI, has become a pass for electronic products to be sold in this market. High efficiency and low power consumption have become one of the important factors that must be considered in the research and development process of home appliances. In addition, as the volume of electrical equipment tends to be thinner, for example, the mechanical thickness of LED ultra-thin TVs is no longer ...
