LED Driver for Home
Divya Mary Abraham | Deepa K [5]
Abstract: Among the most recent technologies in lighting devices and lamps, LEDs have an increasing number of application niches. Every day, they are becoming more popular and more accessible to the general public. LEDs are unable to regulate their own current, being essentially constant-voltage loads. Since LED light output is directly dependent on forward current, this means that LEDs require a current regulating driving circuit, which performs a function similar to that of a ballast for discharge lamps. Here an LED driver for home application is presented. This converter can be derived by integrating the totem-pole bridgeless boost power factor correction (PFC) circuit and half-bridge LLC resonant converter. Therefore, the number of semiconductors in the line-current path can be significantly minimized, and the power losses in the secondary rectifier diodes and the primary switches can be dramatically reduced. This circuit allows removing the bulky electrolytic capacitors with short lifetime by increasing the bus voltage ripple, and thus, the long lifetime is another advantage of this LED driver.
