摘要: LED technology has been used widely in various applications due to its advantage term of functionality, high efficiency, low cost, small size and reliability. In order improve performance prolong LED's life, High Power driver is developed. control output voltage by using current mode controlled method. This development can increase the operation provide protection, decreases lastly make possible user friendly installation. Voltage source step up boost converter as main circuit. circuit, regulate characteristic LED. LTC 3783 PWM controller drive gate pulse signal MOSFET. designed operate load that consists 6 units each rating 5 Watt connected series. Theoretical calculation made obtain component specification. The LTspice software simulate circuit calculated parameters before move on hardware implementation. Eagle design Printed Circuit Board (PCB). Then, all components are mounted PCB which FR4 material. built tested experimentally waveform recorded.
