Method for controlling a static power conversion unit and induction heating system for cooling appliances using such method

摘要

In a method for controlling a static power conversion unit to an inductor, particularly for an induction system used in cooking appliances, the value of an electrical parameter of the circuit is monitored at predetermined time intervals and at a predetermined duty cycle of the power transistor switching frequency, and on the basis of the monitored value, the duty cycle is modulated accordingly between the predetermined time intervals in order to keep the delivered power at a predetermined constant value.
