SYSTEM 150-degree control of slave voltage inverter with pulse-width modulation

摘要

The proposed technical solution relates to electrical engineering, in particular to power electronics and can be used to control the three-phase voltage inverter driven intended for booster power devices. It is proposed to 150-degree control system voltage inverter driven by a pulse width modulation. This system comprises a unit forming a special signal different from the other analogues, a frequency multiplier generates an output signal frequency to a multiple of the network frequency and the number of phases. The technical result of the solution of the problem is to improve the harmonic content of the voltage, by obtaining a five-step voltage waveform against a known three-stage inverters from 180-degree control algorithm and pulse width modulation.
