A Study on the Driving Characteristics of Delta Inverter Driving Induction Motor Control System Based on the Microprocessor

마이크로 프로세서에 의한 델타인버어터 구동 유도전동기의 운전특성에 관한 연구

This paper presents a study on the driving characteristics or delta inverter driving induction motor control systems based on the microprocessor. Delta inverter is a novel circuit which uses only three power transistor. Requiring approximately hair the components or a conventional bridge inverter it therefore has a merit of coat and Simplicity. The basic operating principles of the delta inverter and conventional bridge inverter are argued, using resistive and inductive load. Sinusoidal PWM method uses to reduce the harmonic components of its output waveform to acceptable levels.
