Technical Electrodynamics| Summary: | The analytical method of estimation of inverter output voltage harmonics is developed. The universal formulas that describe equivalent circuit of inverter are obtained .These formulas give a possibility to calculate the optimal commutation angles of inverter semiconductors switches that provide the minimal Total Harmonic Distortion of multichannel inverters as function of channel number and characteristics of power supply. The formulas can be used as for 3- phase systems with neutral, so without neutral. Two types of power supplies are analyzed: with constant voltage and with pulsed one (supplying by rectifier). The developed mathematical models permit to design powerful multichannel inverters with demanded electromagnetic compatibility with another power electronic devices connected to common main.
