Numerical Circuit Analysis of a Magnetic Oscillation Type Sinusoidal Inverter

摘要

This paper describes a circuit analysis of a magnetic oscillation type sinusoidal inverter. The inverter is connected to an ac voltage source such as the line power, and can supply electric power easily to the ac voltage source. The inverter utilizes a magnetic oscillation circuit constructed with power transistors and a nonlinear magnetic core. In order to quantitative analysis, we present a simulation model of the magnetic oscillation circuit based on a general purpose circuit simulation program "SPICE". The simulation results of the oscillation voltage and current waveforms agree well with experimental ones.
