Abstract

The invention discloses a mains supply switching circuit for an interactive inverter. The mains supply switching circuit comprises a voltage comparison circuit and a switch switching circuit, the voltage comparison circuit comprises a rectifying circuit and a voltage comparator, the input end of the rectifying circuit is connected with the mains supply, and the output end of the rectifying circuitis connected with the input end of the voltage comparator; the switch switching circuit comprises a switch circuit and a switching circuit. The input end of the switching circuit is connected with the output end of the voltage comparator; wherein the switching circuit comprises a first input end, a second input end, a control end and an output end, the output end of the switching circuit is connected with the control end, the first input end is connected with commercial power, the second input end is connected with the inversion loop, and the output end is connected with a load. According tothe invention, the interface resource of the MCU (or the control chip) is not occupied, and the commercial power switching purpose of the interactive inverter can be realized by means of simple components through the voltage comparison circuit and the switch switching circuit.

Description

technical field [0001] The invention relates to the field of commercial power switching based on an interactive inverter, in particular to a commercial power switching circuit and method for an interactive inverter. Background technique [0002] Inverter (inverter) is a device that converts direct current into alternating current (generally the mains voltage, the waveform is sine or square wave). The DC power used is a battery, and the photovoltaic inverter uses a combination of solar photovoltaic panels and batteries. as input. From the perspective of the input side, inverters or photovoltaic inverters are divided into two types. One type does not need to rely on the mains power, and converts the electric energy of the battery into the mains power to supply power to the electrical equipment (load). The battery of this type of inverter must be charged by other charging equipment or by photovoltaic panels. The other type is an interactive inverter with a mains input and an ...
