摘要
Systems and methods of quasi-resonant induction heating are provided. In particular, an induction heating system having quasi-resonant inverters in an induction cooktop for improved controllability of multi-channel quasi-resonant inverters. The inverter can include an induction heating coil configured to inductively heat a load with a magnetic field, and a power supply circuit configured to supply a power signal to the induction heating coil. The inverter can further include one or more switching elements. The inverter can further include a resonant capacitor coupled in parallel with the induction heating coil. The inverter can further include having separate rectifiers in each channel to improve controllability.
