4/1/2024 0 Comments Mosfet coil driver circuit![]() Due to its ability to convert the input DC into sine wave rather than sawtooth signal (from 555 driver circuit), hence the noise or the transformer's hum can be reduced or sometimes, entirely eliminated at all. This driver is called zero voltage switching driver cuz it switches current exactly when the voltage across the MOSFET equals zero, and give a pure sine wave output, hence behaving like an DC-AC converter or 'inverter'. The most popular ZVS flyback driver nowadays amongst hobbyists is that designed by Vladimiro Mazilli. ![]() Hence, i turned to ZVS from that instance. Therefore, when i was searching for a more robust flyback driver in order to use it as my tesla coil power supply afterwards, i realized that zero voltage switching (ZVS) flyback driver can give high voltage without heating the MOSFET too much ( sometimes even none!). I ve broken about 3-4 MOSFET since i ve been using it. ![]() Though the 555 driver i ve been using is quite good in running the flyback, however the MOSFETs were easily heated up. ![]()
