Generating 470kHz 400W 220V High Frequency AC for Electrosurgery Board Design

Hi, I want to know that how can I generate radio frequency alternating current for designing an Electrosurgery board or suggest me what should I do to design this board with the following requirements
Frequency-470KHz
Power-up to 400 Watt
Voltage-220 Volt

Hello
A simple solution is to generate a square wave frequency with a power SiC MOSFET. The load can be inductive or resistive. The high power output certainly contains many harmonics of 3, 5, 7, etc, being the square wave. You can therefore connect an RC filter to the output to eliminate harmonics and obtain an almost perfect sine wave. Remember that the MOSFET needs a small high-frequency driver to be driven. Search the Internet for a SiC or Gan MOSFET working at that frequency.

Thanks for the solution. Its really worked for me.
