| Abstract |
This study deals with selection method of a high-frequency transformer in a zero current switching(ZCS) based resonant converter for non-starting air conditioner compressor in commercial vehicles. It describes the selection method of the core/winding materials to reduce skin effect, the winding ratio to obtain the stable output voltage and (Product Area) for the high-frequency transformer. Selected transformer is modeled as a MAXEWELL, and confirms the leakage magnetic flux distribution. The result of applying the selected transformer to resonant converter, it can be seen that good resonance between transformer inductance and voltage doubler capacitors, stable 250V output voltage under 2.5kW load condition. It was confirmed that the favorable operating characteristics in the transient state which the load changes rapidly from 2.0kW to 2.3kW. |
