A Half Bridge CLL Resonant DC/DC Converter

Abstract

A CLL topology suitable for low voltage, low/medium power application, has been investigated in this paper. It has been shown that the topology is having load-independent characteristics, when fed from constant DC voltage. However, in practice, because of the circuit non-idealities and to compensate for the change in the input voltage, frequency variation is required. The performance of the converter has been presented. Preliminary experimental results are also produced from laboratory prototype to confirm the characteristics obtained analytically.
