N2 - A new class of high-voltage-gain DC-DC converters for high efficiency and transformer-less DC-DC applications where large voltage step-up ratios are required, is presented in this paper. The converter is derived from the hybrid integration of a switched-capacitor converter and a boost converter. It features high step-up voltage conversion ratio with a moderate duty cycle; non-pulsating input current; low voltage stress on all of the switches; easy implementation of control and driving circuits; scalability for high current high-power applications; and low cost due to reduced components via combination of a two-stage converter into a single-stage converter. Full soft-charging operation and minimal device voltage stresses are achieved under all operating conditions. Steady-state operations of the converter are comprehensively analyzed. A 300 W prototype of a 19-time converter achieving the peak efficiency of 96.1experimental results validating the theoretical analysis and operation of the converter are provided.
