This circuit is formed according to the principle of positive breakover convertor. That is to output power to load when the transistor is breaking over. We add diode D1 in its loop for the purpose of overtop base-emitter voltage on transistor. Start-oscillation button connected betweent resistor R1 and R2 is assisted start device. Meanwhile it can prevent the add of base current when load current is increasing. So this circuit has the function of short circuit protection.The data of transformer:winding n1=40 turns, 0.32 copper enamelled wiren2=12 turns, 0.15 copper enamelled wiren3=420 turns, 0.1mm copper enamelled wire (View)
