Resonant converter, which were been investigated intensively in the 80's [B1]-[B7], can achieve very low switching loss thus enable resonant topologies to operate at high switching frequency. In resonant topologies, Series Resonant Converter (SRC), Parallel Resonant Converter (PRC) and Series Parallel

A. LLC Resonant Converter Voltage Gain Review The half-bridge LLC resonant converter prototype is shown in Fig. 1. The operating frequency range of the LLC PFC is defined as fp ≤ fs ≤ fr, where below-resonance operation is preferred to ensure the inductive impedance characteristics of the LLC resonant tank, so that the soft

If LC filter is not well damped, the frequency response will peak near resonant frequency, which means the LC actually is amplifying the noise signal. Apart from the amplification, sometimes, LC filter design also has effect on the control loop of the DC-DC converter, some poor LC filter will decrease the phase

So what are the values of C1, L1, C2, etc.? The answer isn’t simple. We start with a quality variable capacitor for C1 as described below. For various reasons, C1 will probably be
