The recent growth of battery powered applications and low voltage distributed energy sources, the high voltage gain DC-DC converter becomes a necessary part. Here, voltage multiplier cells are integrated with the classical non-isolated dc-dc converter in order to obtain high step-up static gain and reduction of maximum switch voltage. The diodes reverse recovery current problem is minimized and voltage multiplier operates as a regenerative clamping circuit. The operating principle, the design procedure, simulation model and results obtained are presented. A boost converter with one voltage multiplier stage was tested, for an application requiring an output power of 50 W, operating with 16 V input voltage and 80 V output voltage. The converter easily obtained high gain with low output voltage ripples and reduced switch voltage stress and obtained an efficiency equal to 92.55%.
