Abstract

SPWM (Sinusoidal Pulse Width Modulation) waves are commonly used in the control of frequency conversion and test system. This paper presents a method which can control SPWM waves rising/falling time for the requirements of controlled edge. This function mainly for a high power device test systems. First, SPWM waves are generated by a generator programmed by LabVIEW, and the SPWM waves´ dead time and frequency of carrier signals and modulation signals can be easily regulated by LabVIEW. Second, SPWM waves rising / falling time is adjusted by edge controller. The experimental results indicate that SPWM waves edge time adjusts from 0.1μs to 12μs can be achieved using this design.
