A low-power control circuit

Abstract

The invention provides a low-power consumption control circuit, belonging to the field of power control. The invention comprises a single chip microcomputer, Locking unit, Control unit, rectifying unit, a voltage conversion unit and a voltage detection unit, wherein the output end of the single chip microcomputer is connected with the input end of the locking unit, The output end of the locking unit is connected with the input end of the control unit, the output end of the control unit is connected with the input end of the rectifying unit, the output end of the rectifying unit is connected with the input end of the voltage conversion unit, and the input end of the single chip microcomputer is connected with the output end of the voltage conversion unit and the output end of the voltage detection unit respectively. The invention has the beneficial effects of saving energy and realizing almost zero power consumption of the load in the off-state or standby state.

Description

technical field [0001] The invention relates to a power control circuit, in particular to a low power consumption control circuit. Background technique [0002] In response to the requirements of green environmental protection, in addition to saving energy in the working state, the power load should also reduce power consumption as much as possible in the non-working state, that is, the standby state. However, in the actual application process, even if the auxiliary circuit two-stage configuration and the intermittent operation mode of the PFC stage are used, the so-called "zero power consumption" cannot be achieved, and long-term use will cause waste of resources. [0003] Taking LED lamps as an example, LED lamps are widely used in daily life because of their high efficiency, environmental protection and long service life. In traditional LED applications, since there is no standby condition during the working period of lighting applications, they are dedicated to standby p...

However, in the actual application process, even if the auxiliary circuit two-level configuration and the intermittent operation mode of the PFC level are used, the so-called "zero power consumption" cannot be achieved, and long-term use will cause waste of resources.

[0003] Taking LED lamps as an example, LED lamps are widely used in daily life because of their high efficiency, environmental protection and long service life. In traditional LED applications, since there is no standby condition during the working period of lighting applications, they are dedicated to standby power supply Auxiliary power stage is not suitable, switching power supply for bulbs is still connected to the grid and draws energy even when there is no lamp or the lamp is damaged, causing power loss
