Abstract :
A bi-directional resonant DC link (RDCL) converter is presented for use as a variable frequency to variable frequency (VF-VF) sinusoidal three phase power converter for aerospace (aircraft) applications. Three phase sinusoidal input up to 750 Hz and sinusoidal output up to 400 Hz is achieved using second order filters on the input and output of the converter. The results demonstrate active damping of the input and output resonance conditions. Input and output conducted current emissions, which contribute to inductively coupled EMI, are shown to be low. High efficiency, high power density, small DC bus capacitance and unity input power factor are some of the attributes of this converter topology
