Induction stove

00:13:02

A highly simplified model of a induction cooktop. The resistor and secondary of the transformer are actually the metal pot itself.

25kHz -&gt; 40 us is the resonant frequency, reaching 118A RMS (1.4kW of heat in the pot itself).

Many cooktops increase the frequency to reduce power. Try lowering the period of the control signal and see what happens

Estimated efficiency (25kHz): 87%
Estimated efficiency (100kHz): 43%
