Abstract

PURPOSE:To enable the control of phase stably and precisely over arbitrary fre- quency ragne by using a digital controller for a phase controller. CONSTITUTION:A digital signal is stored in an inverter output waveform data memory RAM14. Then, it is stored in the RAM14 in advance through a digital input interface 13A or the analog input interface 13B by a program for storing in the RAM12, and a PWM sinusoidal wave is directly outputted on the basis of the set frequency and voltage values to pulse amplifiers 16a, 16b, 16c with the programmable timers 15a, 15b, 15c as interfaces.
