T type parallel resonant DC DC converter for high voltage application
In this paper, the use of the T Type cell in parallel resonant dc dc converters, for high voltage power supplies realization is investigated. The proposed converter share same benefits of the traditional full bridge dc dc converter, such as zero voltage switching on primary side switches over wide load range, symmetric three level voltage across the transformer primary winding, integration of transformers leakage inductance and winding capacitance during its basic operation. However, only two switches are subjected to the input voltage, while the other two switches are subjected to half of the input voltage. Theoretical analysis, commutation analysis and design guidelines are presented. Simulation results of a high voltage power supply of 2kW, 400 Vdc input and four high voltage outputs validates the theoretical analysis.
