Make inverter 5V to 220V just₹120 This inverter can use comments 4.7K ohms resistance, Z44 n-channel MOSFET, 2Amp 12-0-12 transformer, 5Volt DC supply Bulb and bulb holder.

Make inverter just 1 transistor

Make Inverter 1.5volt to 220volt Hello wellcome to science and technology discovery. This inverter make just  ₹15 .  This inverter operated 220V  9watt  60HZ bulb.  This transformer you can get old mobile phone adaptor.  This type of transformer 6 legs, you can check transformer using Multimeter  Setmultimeter 200 ohm and check frist 2 pin 3.6 ohm to 5.6 ohm, second next 2 pin 1.2 ohm, third next 2 pin 0.8 ohm. This  inverter operated transistor 2N3055 NPN transistor frequency 2.5MHz, DC collector current 15A. Power Dissipation pd 115 watt. DC current gain hFE 20. Using resistance 33 ohm to 1K ohm +-5% you can use.
