500W Power Inverter Circuit based TIP35C

This is the 500W power inverter circuit, converting a 12VDC battery (usually car battery) to become 220-240V AC power. The inverter is powered using 6 pairs of transistor TIP35C which connected in parallel, so it will be 12 TIP35C transistors.

There is certainly only one variable resistance in this circuit diagram which is made use of to adjust frequency of 240V AC output current. It is best to have a frequency meter to adjust this frequency of 50HZ to 60HZ as per your requirement. Please don’t power up any device using your inverter just before frequency adjustment for the reason that a wrong AC frequency can burn your equipment as well as your inverter.
