Abstract

This paper presents a 4th order CLCL resonant converter that has a simple and unique design, and also it has the constant current power supply characteristic that is used for many constant current applications in various laboratories and industries. This converter is designed with Immittance two inductors and two capacitors, to property for constant current power supply. A detailed analysis, design and control process of a 200w converter is given, and simulation results are verified with results of a constructed converter. This converter with its unique structure, a combination of series and parallel resonant converter, has the advantages of both. As a constant current supply, CLCL resonant converter has the advantages of rigidity against short circuit even without a controller, easy operation in parallel mode, low circulating currents and high efficiency due to its soft switching operation. For this converter, leakage and magnetizing inductance of a transformer can be used as a part in the resonance network, and it decreases the converter size. Furthermore, series capacitor, eliminates the DC component and prevents the transformer saturation in unbalance conditions. With fixed-frequency performance, filter design also will be easier. Considering these advantages, the proposed topology can be used in a variety of applications such as magnetic power supplies, capacitor charging power supplies and agitator for laser diodes.
