Standard N-channel MOSFETs serve as highly efficient solid state switches in high-voltage systems. Designed specifically to handle hard switching, these metal-oxide–semiconductor field effect transistors also work well in resonant mode applications. Common uses for N-channel MOSFETs include dc–dc converter, electric motor controller, and pulse generator for a laser or x-ray machine.
