Abstract
A three-level Cuk converter with coupled inductance is proposed in this paper. Based on the research and design of existing three-level Cuk converter and Cuk converter with coupling inductance, this paper combines three-level technology with coupling inductance, which is called the “three-level coupled inductance Cuk converter” in this paper[1-3]. Compared with the existing converter, it has the advantages of boost capability and energy conversion efficiency. This kind of converter integrates the low voltage stress of the switch with three-level DC-DC converter and the boost function of the DC-DC converter with coupling inductance[4-6]. The three-level structure reduces the voltage stress when the switch is turned off, while the coupling inductance structure greatly improves the boost capability of the circuit. The working principle and periodic mode of three-level coupled inductor Cuk circuit are analysed, and the mathematical formula of voltage gain is deduced.
