This article analysis the bidirectional operation of the so called Isolated Efficient Wide Range
Converter (I-EWiRaC), equipped with synchronous rectification, including small signal
modelling and controller design. The converter is used in fuel-cell-based back-up systems,
with ultra capacitors (UC) as intermediated energy storage between the fuel cell and the
power converter. Earlier, an additional converter was used to charge the UC to the required
DC voltage. The presented idea can improving the system efficiency and reliability and …
