Abstract :
This paper presents a hysteresis based current control PWM named “Hi-PWM”, which has several advantages such as quick response of current, less fluctuation of switching frequency and less harmonic components. In this paper, the improvement of Hi-PWM is explained, which realizes switching frequency control and output voltage calculation. This paper also shows simulation results driving induction motor with Hi-PWM.
