Inverter for florescent lamps. This really is a single transistor oscillator circuit. The electric current passed via primary winding inducts a magnetic field to the core and the core provides the power back to the feedback winding having a delay determined by the core material and windings. System then oscillates continuously on a frequency determined by this timing. It’s not possible to use 2SD882 with voltages more than 4.5 volts. It is only necessary in case you are going to supply the circuit with only 4.5 volts. Equivalent transistors may possibly not work as great as 2SD882.
