Annotation: A synchronous time-pulse method to control a resonant inverter with a serial capacitive load compensation is proposed. The comparative analysis of synchronous and asynchronous method for controlling the voltage inverter is carried out. It is shown that synchronous control provides the soft switching of power transistors with energy circulation in the load resonance circuit of the voltage inverter. The method allows to reduce the total loss capacity of inverter or to increase the frequency of conversion.
