POWER CONVERSION CIRCUIT FOR DRIVING A GROUP OF LIGHT EMITTING DIODES

摘要

A power conversion circuit that may include at least one inductor, a switching unit, multiple capacitors and a rectifier for rectifying the alternating input signal; wherein the multiple capacitors comprises a set of isolating capacitors that comprise a first isolating capacitor and a second isolating capacitor; and wherein the set of isolating capacitors is configured to: (a) provide a capacitive isolation barrier between a first input port and a first output port and between a second input port and a second output port; and (b) participate in a resonant or quasi-resonant power conversion across the capacitive isolation barrier.
