Using BJTs could be very reliable and simpler but quiet bulky, if space is your problem and need the upgrade from low to high power inverter in the most compact way, then mosfets becomes the. .
The above explained ideas for upgrading a low power inverer circuit to a higher power version can be implemented to any desired level, simply by adding several MOSFETs in parallel.. Yes, an inverter converts low voltage DC (direct current) into high voltage AC (alternating current) power. For example, it can take 12, 24, or 48 volts DC and convert it to 230 volts AC1. High voltage inverters are commonly used in applications such as solar energy systems, where they convert the DC electricity from solar panels into AC electricity suitable for home use or feeding into the grid3.
