Abstract |
Inductors for power electronic converters resonate at a self-resonance frequency due to the presence of parasitic capacitances. Beyond the resonance frequency, the impedance of the inductor demonstrates capacitive nature and hence will provide a low impedance path to high-frequency noise components. In this paper, self-resonance frequency of the inductor for an HSU converter has been evaluated by the application of FEA models. Simulations are performed under different design scenarios to optimize the inductor for high frequency performance. Results showed that the self-resonance frequency is increased by the size of core and decreasing the number of turns. However, power density of converter puts a maximum limit on the size of the core. Also, this study provides an approach to optimize the gain of converter as results showed that the inductor design for higher voltage gain has lower self-resonance frequency. |
