Induction Heater Uses New Coil. 14 Comments . by: Bryan Cockfield. June 8, 2022. Title: ... and uses a driver circuit called a Mazzilli ZVS driver running through some power MOSFETs to power the ...

While the electronics for a resistive heater are just a beefy power supply and a MOSFET, [Z] is using 160 kHz AC at 30 V. That’s a much more difficult circuit to stuff on a printer controller board.

Induction cookers will have protection circuitry incorporated to guard against the “no pan” condition. 2. Illustrated is an equivalent quasi-resonant RLC circuit.
