Gate Driver Optocouplers in Induction Cooker (4) – Finish

Summary
In this article, the half-bridge series resonant and quasi resonant induction cooker topologies along with three gate driver methods were discussed. In order to reduce the design size and audible switching noise while improving power efficiency, these resonant converters are chosen.

The discrete transistor gate driver circuit is cost effective but increases design complexity while providing no safety isolation. The gate drive transformer consumes board space due its size and requires additional work and cost to achieve higher switching duty cycle above 50%. Finally, gate drive optocoupler integrated ICs saves board space through high level feature integration while providing high voltage safe isolation and noise immunity all in one package.
