Abstract

This paper presents a self-oscillating electronic ballast for a 36 W LED string. The design consists of a simple control that reduces the component number and cost of the ballast. Self-oscillating converters are popular in compact fluorescent lamps; therefore, it is proposed the use of this self-oscillating control technique for the LED lamp. The self-oscillating LED driver represents a very suitable solution in compact LED products. This paper describes the design of a self-oscillating electronic ballast at high frequency. The output of the sine wave of the resonant inverter is rectified and, then its high frequency yields a reduction in the value of output capacitor.
