Paper Abstract

In this paper, we realize an advanced inverter system consists of a reference oscillator, a discrete type arithmetic operation circuit and a switching circuit. The arithmetic operation circuit determines the switching timing (PWM pattern) automatically on the basis of the time sequence data of the difference between the current and the reference signal. This circuit is synthesized by using bang-bang servo technique and it can be implemented by using several BBD elements and operational amplifiers. This circuit is valid for fairly wide change of the magnitude and frequency of the reference input and some variation of the load impedance.
