Abstract
A hybrid converter achieves high efficiency with an inductor positioned at the lower current path that significantly decreases inductor loss by having the DC component of inductor current reduced. The circuit also features reduced inductance requirement by reducing the voltage swing blocked by the inductor. As a result, it turns to benefit of both efficiency improvement and better integration. Less voltage stress for switches is also an important advantage to switching loss reduction and switching frequency increase which in turns enables passive component size reduction. The circuit in this invention can be realized for both step-down and step-up power conversion as well as bidirectional power flow is available. For simplicity and cost, some of switches can be replaced with passive switches such as diodes which highly simplifies the converter circuit implementation.
