Problems solved by technology

With this energy-saving control method, although the power consumption of the inverter is reduced, the inverter is still in the working state, and the battery power will be exhausted soon.
[0005] To sum up, none of the existing inverters can fully realize zero power consumption, so there is an urgent need for an inverter with energy-saving control function, which can truly achieve zero power consumption during energy-saving control

Abstract

The invention discloses an inverter output energy-saving control system and method. A first switch control unit is turned on or off through a self-recovery switch and a signal sampling detection unit, and a switch detection signal and a voltage detection signal are sent to an MCU control unit; the MCU power supply unit is turned on or turned off through the first switch control unit; the MCU power supply unit supplies power to the MCU control unit; a load signal of the inverter is detected through an AC output voltage and current power signal acquisition unit; and the MCU automatically closes the energy-saving control system and the inverter through the first switch control unit and the second switch control unit according to the switch detection signal, the voltage detection signal and the load signal. When the inverter has no load, the loss of the inverter is close to zero, energy is saved, and the inverter has high practicability.

Description

technical field [0001] The invention belongs to the field of inverters, and in particular relates to an inverter output energy-saving control system and method. Background technique [0002] The inverter is a voltage conversion device that converts DC power into AC power. The DC power is generally a battery, and the AC power is generally AC100V-240V, 50Hz-60Hz pure sine wave or modified wave. [0003] Generally, the AC output of the traditional inverter does not have voltage and current detection. When the power switch of the inverter is turned on, the inverter always has an AC voltage output. When the AC output of the inverter is not connected to the load, the equipment is always running. In this case, the electric energy of the battery will be exhausted quickly, resulting in a large amount of waste of electric energy. [0004] At present, there are also low-power inverters on the market. The power consumption of the inverter is reduced by detecting the AC output load of t...
