  1. hai
    any body help me on single phase 220volt ac to single phase ac220 volt control voltage and control frequency circuit, its very very urgent dear please please sent me as early as posible on my mail.

  2. thanks for the diagram and explanation, pls i wouldnt know if you have the circuit diagram for a 1kva inveter, i do have one, but the exact MOSFET and transformer values are what i am able to get. it converts 24vdc to 220vac, and also allows the reduction and increase of the voltage. if you do have a diagram of a 1kva inverter, pls share it with us…thanks

  3. those components are placed offside the PCB
    you may connect the T1 and diodes using cable. The q5 and q6 placed aoutside the PCB because it require heatsink.You may connect each transistor with the B (basic) and E (emitter) on PCB. The C (Collector) connected to the T1.

  4. hello i dont understand pcb layout regarding q5(2N3773),q6(2N3773),t1(tansformer),d7(IN5404),d8(IN 5404)beacuse i have not found on pcb lay out

  5. hi guys can you please help with the projects that i have to design which is 300W 12V to 220V inverter with automatic switch over
