Abstract
- This paper presents the design of a medium-power-rating isolated power supply for ultrafast tracking converters and MOS-gate driver circuits in medium- and high-voltage applications. The key feature of the design is its very low circuit input-to-output parasitic capacitance, which maximizes its immunity from noise due to fast changes in voltage. The converter is a voltage controlled current source, utilizing a transformer with extremely low interwinding parasitic capacitance, which is achieved by separating the windings by a significant distance. Experimental measurements show that an overall circuit input-to-output parasitic capacitance of 10 pF in a 300-W prototype can be achieved. The circuit input-to-output capacitance per watt is therefore 30 times lower than that of existing approaches. A mathematical model of the interwinding capacitance of the proposed transformer, circuit analysis, and experimental results are provided to prove the feasibility of the converter.
