Detailed modeling of the Limpaecher-design resonant power converter

We present the results of a detailed assessment of the operating characteristics of the Limpaecher-design resonant power converter as studied by using a simulation model. The study shows that, from the perspective of the power system, the Limpaecher design yields low harmonic distortion (<3%) and high power factor (>0.99). From the perspective of the load, the high frequency of power conversion allows both low ripple (1.7%) and a small stored energy at the output (1.6 kJ), benefits that are oftentimes mutually exclusive. The cost of these performance advantages lies in a multitude of semiconductor power switches, a somewhat complicated control algorithm, and a critical transformer design
