Abstract
This paper presents a self-oscillating electronic driver for a 36 W LED string. The design consists of a simple control that reduces the component number and cost of the driver. 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 driver at high frequency. The output of the sine wave of the resonant inverter is rectified. This LED driver not require of electrolytic capacitors, because LED is operated with pulsating output current.
