Inverter 12V DC to 240V DC

Inverter 12V DC to 240V DC circuit diagram

This inverter 12V DC to 240V DC can be used to power electric razors, stroboscopes and flash tubes, and small fluorescent lamps from a 12 volt car battery. In contrast to the usual feedback oscillator type of inverter, the oscillator of this inverter is separate from the output stage, which allows easy adjustment of the oscillator frequency to suit different applications.

The oscillator circuit consists of a 555 timer connected as an astable multivibrator. The inclusion of D1 ensures that the duty-cycle of the squarewave output is maintained at about 50%. The output of the 555 drives the base of T1 which switches current through one half of the primary of the transformer. T2 is driven from the collector of Tl and thus switches current through the other half of the transformer winding on opposite half cycles of the drive waveform. Zener diodes D4 and D5 protect Tl and T2 from any high-voltage spikes generated by the transformer.

The voltage applied to the transformer primary is stepped up and the required high output voltage appears across the secondary winding. Depending on the application the secondary voltage may or may not be rectified.

  1. Hello Sir! can U help me schematic of inverter of 12v Dc to 240v Ac using 555 timer

    because i can done the final thesis on this title pls help me .

  2. please sir can u kindly give me the diagrams for 24v-230vac and 12v-230vac 60hz, and the specifications for it? and the output power? also the parts? thanks a lot sir more power
    my email is

  3. Please Sir.
    Accept my greetings and also to the entire forum, i am still starting Inverting circuits, Can i please ask this page a simple 12v to 230v DC to AC inverter schematic that can deliver 200watts?? Please i am not very good in it, i am new, if i can also get help on how wire the transformer like many turns to wire will the Primary take and the secondary of the output transformer i will appreciate it. my email address is ( Any help will be appreciated.

  4. i need a complete circuit diagram of 12v DC inverter circuit with an output of 230v AC.this my school project.thanks

  5. or i want to again some inverter ossilator shematic diagrams then details pin voltage or confrigration if u have possible sir send me my mail side []

  6. hi sir i want to shematic diagrams of only for colour television 21” to 29” loader inverter diagrams pls sir send me anyway by sir [ this is my id can u send there sir thanks sir
