Conventionally, electrolytic capacitors (EC) are necessary at the output of a LED driver to reduce output ripple and maintain overall system performance. However, the use of ECs shortens the lifespan of LED drivers. This thesis tests and compares the circuit performance of LED drivers with EC, with film capacitor and without output capacitor. According to experimental verifications, the studied single-stage LED driver offers the advantages of high-efficiency, high-power factor and low circuit cost.
