ABSTRACT:
A pulsating current inverter control circuit aims to convert AC power provided by an external electric source to a pulsating current through a rectification unit. The inverter has a control unit outputting an operation frequency to an actuation unit to divide the pulsating current to a plurality of electric pulse waves to drive a transformer to perform voltage transformation and drive a load. An inspection unit has a preset reference electricity value to compare with the pulsating current and output an activation signal and a deactivation signal to activate or deactivate the actuation unit. The transformer stops performing voltage transformation while the actuation unit is deactivated. Thus the transformer can output power to drive the load. The inspection unit can output a comparison signal to the control unit to alter the conductive interval of the operation frequency so that the inverter can output steady electricity in different AC environments.
