Abstract

The geometrical algorithm for generating a 3-phase SPWM signal for VVVF (Variable Voltage, Variable Frequency) inverter drives is proposed. In this techniques, it is suitable for micro-processor based implementation since the pulsewiths are computable in real time from simple analytic expressions. System hardware consists of the inverter circuit and the 3-phase SPWM signal generating circuit. The inverter circuit is a 3-phase SPWM signal generating circuit is single board micro-processor consisting of Z-80A CPU, EPROMXI, CTC, PIO. The method of controlling VVVF at the inverter output is discussed here.
