How do I choose the right MOSFET for a high-efficiency inverter circuit?

[Kruti Bhinde]

Help me with best strategies to choose correct MOSFET for a HF inverter that I am designing.

Conduction loss is larges loss in a MOSFET, it occurs when the MOSFET is in the 'on' state and current flows through its channel. It's calculated using the formula: P = Current^2 × Rds. Also switching losses occur during switch the transistor on and off.

Look it this calculator and you will see how large conduction losses are compared to the other losses. https://www.dmcinfo.com/latest-thinking/blog/id/10517/mosfet-power-loss-calculator

The LTspice circuit simulator has a large number of MOSFETs listed. If you post what voltages and currents you are interested in I could see what is listed there. It would benefit you to learn to use the simulator for your work.

The selection depends on your inverter's specifications.
