A Survey On Advance Approach for Power Efficient LED Driver for LED String using DC-DC Converter

POWER ELECTRONICS CONVERTER

Current generation DC source use everywhere instead of AC because of Power consumption and leakage current. So in this Project work on hybrid passive filter base cascade DC-DC converter which design with capacitor less. So we design converter to drive DC LED string with minimum power consumption and also work on load balancing mechanism, Design module and analysis on MATLAB (SIMULINK) & work on other parameters like power consumption loss and energy also work on the design is based on the utilization of the internal capacitance of the LED to replace the smoothing capacitor. LED lighting systems usually have many LEDs for better illumination that can reach multiple tens of LEDs. Such configuration can be utilized to enlarge the total internal capacitance and hence minimize the output ripple.
