Which power semiconductor is preferred for the given application? MOSFET or IGBT?
Bidirectional DC DC converter for hybrid storage devices like battery and supercapacitor with Solar harvesters for motor drive application with following specifications:
Battery parameters: 24VDC Output Parameters: 1kW, 48VDC with maximum current drawn is 25A.
Switching frequency is not decided. What all things to consider in selecting the switching frequency?
Switching frequency is an important parameters for selecting the power switches whether MOSFET or IGBT.
IGBT's are preferred when high current and low frequency, IGBT can perform well in low frequency range (up to 30KHz).
MOSFET's are work well in high frequency operation with low current(up to 100A)

Thanks. But what are the necessary things to consider in selecting the frequency? Except sizes of the passive elements and switching loss, which frequency is suitable for above said application?
