I NEED A SIMPLE CIRCUIT FOR A 2N3055 TRANSISTOR HOW TO

Start with a slow pulse rate and the minimum ON time, use a an old car spark plug as a load for the EHT, adjust the dwell/ON time until you get the 'best' spark for the lowest ON time. In this post we learn how to make a simple variable power supply circuit using transistor 2N3055 and some other passive components. Use a Proper heat sink to fix both transistors because high current transistors get hot. 2 power Transistor 2N3055 is used in this circuit to control the output current. Also make the 'dwell' time and the drive pulse rate adjustable. Use the 5k potentiometer for the adjustment of voltage and the 10k potentiometer with BD139 transistor for adjustment of current.

The Cathode of the Zener to the collector of the 2N3055.Ĭonnect also, the Res/Cap as shown in your original diagram.ĭesign the 2N3055 base driver pulse circuit so that the transistor base current is about 200mA. Here we learn how to make a very simple 100 watt amplifier circuit using a 2N3055 transistors and a few other passive components. A method I have used many times and reliable operation is, go to your local car breakers yard and get a 'ballast' resistor.Ĭonnect the ballast resistor in series with the +12v line that goes to the 'IGN' connector on the ignition coil.Ĭonnect the collector of your 2N3055 transistor to the ignition coil that normally goes to the 'Circuit Breaker' contacts on the cars distributor.Ĭonnect a high power, 24V 5Watt Zener across the 2N3055.
