Using Transformer Parasitics for Resonant Converters
- Journal Article
Parasitic capacitances of conventional transformers can be used as resonant elements in resonant DC-DC converters in order to reduce the overall system size. For predicting the values of the parasitic capacitors without building the transformer different approaches for calculating these capacitances are compared. A systematic summary of the known approaches is given and missing links between the different theories and missing equations are added. Furthermore, a new simple procedure for modeling parasitic capacitances that is based on the known approaches is proposed. The resulting equations are verified by measurements on four different high voltage transformers. Show more
