Electronic Ballasts Using the IR215X Drivers


Posted on Nov 14, 2012

In this circuit the switches are power MOSFETs driven to conduct alternately by windings on a current transformer. The primary of this transformer is driven by the current in the lamp circuit and operates at the resonant frequency of L-C. Unfortunately, the circuit is not self starting and must be pulsed by the DIAC connected to the gate of the lower MOSFET.



After the initial turn-on of the lower switch, oscillation sustains and a high frequency square wave (30 - 80 kHz) excites the L-C resonant circuit. The sinusoidal voltage across C is magnified by the Q at resonance and develops sufficient amplitude t

Like to the viability of ballast   Jul 14, 2008

I would to know more details of the Circuite. There will be some operational falts in ares where the voltage is just 100V. I am intrested with this project, but the avilability of raw materials to implement the same. Hope that there will be definite reply to the mail. Thanking you Ajesh. A.P
