Abstract
A power inverter particularly suited for use in applications requiring serially inductively heating workpieces in a predetermined manner, having a main inverter and an auxiliary starting inverter, in an arrangement in which the starting inverter is selectively applied and removed from the load in predetermined timed relationship with the application of the main inverter across the load, and providing a decrease in the inherent instability of the main inverter operation through an increase in the apparent Q of the load, while adjusting the output of the starting inverter to a value greater than the instability level of the main inverter.
