DRIVING APPARATUS OF INVERTER FOR CAPACITIVE LOAD, CAPABLE OF EASILY CONTROLLING THE VOLTAGE AND THE FREQUENCY APPLIED TO THE CAPACITIVE LOAD

摘要

PURPOSE: A Driving apparatus of inverter for capacitive load is provided to extend the life cycle of a capacitive load by reducing the impact current of capacitive load.;CONSTITUTION: A rectifier(110) rectifies the inputted outside AC voltage to the direct current voltage. An inverter(160) changes the direct current into the AC voltage to be applied to the capacitive load. A controller(140) generates the control signal of the inverter to the PWM signal. The controller implements the control to form the output of the inverter as a sign wave of step shape according to the width and the periodicity of the PWM signal.;COPYRIGHT KIPO 2011
