Your project is to design and build a power inverter to convert 12 volts DC to 120 volts AC. A suggested

Please note that this is only a general schematic, and may not be exactly what you need to build in
order to have a successful inverter circuit. Your choice of s pecific power components (transformer, power
MOSFETs, zener diodes) are critical. Paralleled MOSFETs and zener diodes may very well be in order!
