Abstract—Hybrid energy pumping using step-up converters are presented. The voltage conversion ratios of step-up converters are higher than the traditional boost converter or some existing voltageboosting converters. Upon these, by changing the circuit connection or turn-on types of switches, there are three voltage conversion ratios to be generated. Thus, three types of step-up converters to be presented herein. In addition, for any type, isolated gate driver are not used instead of one half-bridge gate driver and one low-side gate driver, and the voltage stress on the low-side switch to magnetise the inductor and the voltage stress on the output diode can be reduced as compared to the traditional boost converter. Furthermore, the basic operating principles of these converters are easy to describe and analyse along with mathematical deductions. The proposed step-up converters circuit is simulated using Matlab/Simulink tool and the results are obtained.
