Systems and methods for reducing noise from quasi-resonant induction control

An induction heating system for an induction cooking appliance, the induction heating system comprising:

• a bus capacitor configured to receive direct current (DC) power;
• a half-bridge (HB) inverter system operatively coupled to the bus capacitor, the HB inverter system configured to energize a first coil based at least in part on the DC power;
• and
• a quasi-resonant (QR) inverter system operatively coupled to the bus capacitor, the QR inverter system configured to energize a second coil based at least in part on the DC power,
• wherein the HB inverter system is further configured to at least partially discharge the bus capacitor based at least in part on a start-up time of the QR inverter system.
