Summary:This paper presents an analysis among three converters that use switched capacitors applied to feed a LED tubular lamp. These converters are designed and simulated and the main results are shown. LED tubular lamps can replace fluorescent tubular lamps with some benefits, such as longer lifetime and less energy consumption. The LED tubular lamp used has power of 23 W, current of 450 mA, input voltage of 220 Vrms, 60 Hz. A topology is proposed aiming to feed the LEDs with the correct current ripple (according to the recommendations). These converters must have high power factor and high efficiency.
