500 Watt Inverter 12VDC to 220VAC

The circuit of 500 Watt Inverter 12VDC to 220VAC is made using a transistor. central component of this inverter circuit is a configuration of 2 pieces of transistors Q1 and Q2 which form a circuit of Flip-Flop. The output of the flip-flop Q1 and Q2 then in severance for each pulse to complement each other using a compiled circuit by Q3 and Q4. Output which complement each other is then given to the driver transistors Q5 and Q6 form the transistor 2SC1061. Power Inverters of this circuit is composed using parallel transistors Q7, Q8 and Q7x, Q8x a form of 2N3055 power transistor 10 pieces. schematic a complete of Inverter 500 Watt circuit can be seen as follows.

Step up part of this inverter circuit using a transformer 12VCT/500VA in secondary and primary 0 - 220V. While the frequency is determined by the flip-flop which is set to 50 Hz.

Note:

• Q7, Q8 and Q7x, Q8x require heat sink.
• Output power of this dc dc converter is around 500 watts.
• An optional 40A fuse can be added in circuit to the 12V supply line.
• T1 can be a 12-CT-12V /250V/40A mains transformer.
