Induction heating cooker with control circuitry for several outputs

摘要

The cooker has transistors to carry out the switching process, triggered by control signals, with diodes and auxiliary resonance condensers in parallel with them. Also in parallel with each of two transistors is one working coil with one main resonance condenser. Auxiliary diodes control the voltage at the main resonance condensers. For a given number of rectifier circuits in parallel with the input filter condenser, twice that number of cooking plates can be operated. The rectifier output signals are controlled in time multiplex.
