Design of New Nonisolated High Gain Converter for Higher Power Density

A high gain nonisolated DC-DC converter using a single power semiconductor switch is proposed in this article. The operation of the explained under continuous conduction mode (CCM), discontinuous (DCM), and boundary (BCM). mathematical expressions for steady-state voltage gain, stress, current stress diodes are provided. Also, design inductors capacitors CCM with appropriate equations. topology tested 200 W prototype at 50 kHz 60% duty cycle. dynamic behavior examined by changing cycle value also load values. verified experimental results to prove effectiveness its operation. provides higher as compared recently developed topologies. efficiency density 90% 1.16 kW/L, respectively.
