Induction heating device

摘要

The device (12a) has a heating frequency unit (22a) e.g. bridge inverter, supplying high frequency alternating current (AC) to an induction heating element (20a) i.e. wound electrical conductor, in an operating mode. A boost unit (24a) converts an input voltage e.g. pulsed direct voltage, into an output voltage that is larger than the input voltage. The frequency and boost units are partially integrally designed. The frequency unit includes switching elements (30a, 32a) e.g. insulated gate bipolar transistors, which are connected in parallel to a part of a rectifier unit (26a).
