Description

PCB For Induction Heating 1000W ZVS 12-48Vdc 20A

Overview

This bare PCB is designed for building a ZVS (Zero Voltage Switching) induction heater driver using two high-power MOSFETs. The circuit supports operation up to 48V input (53.5V maximum) and can deliver up to 1kW output power when assembled with appropriate components and cooling.

The board layout is optimized for high current operation and supports large resonant capacitors and power components typically used in induction heating systems.
