Abstract

The invention relates to a sine wave inverter which comprises a uH-grade 10A high-power inductor, a high-power field-effect tube, a power diode, an MCU (Microprogram Control Unit), a uH-grade 2A high-power inductor, a voltage feedback network, a 2uF-220uF/400V aluminum electrolytic capacitor and a photoelectric relay. The sine wave inverter has the converting efficiency of 99 percent and low cost, saves energy and completely replaces the traditional inverter product with low converting efficiency.

Description

technical field [0001] The invention belongs to the field of power electronic technology inverters. Background technique [0002] In the field of inverters, the conversion efficiency of sine wave inverters is generally around 80%. There is no device that uses photoelectric devices to realize inverters. However, for ordinary inverters using MOSFET power field effect tubes, since the device itself consumes a lot of power, the conversion efficiency will not be affected by more than 80%. Contents of the invention [0003] The conversion efficiency of the inverter is a crucial technical issue. The higher the conversion efficiency, the more energy can be saved. The current conversion efficiency below 80% can no longer meet the needs of the society. In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: use high-power photoelectric relays to form an inverter bridge, use MCU as the controller, and the MCU also reali...
