A comparison is made in this paper between three high voltage gain converters. The first one is a boost converter with an additional level including a coupling inductor for increasing the voltage gain. The second is a converter that is capable to be extended to N parallel converter and the third one uses a clamp circuit to increase gain with a coupled inductor. Three converters are compared in voltage and current peak value and utilization coefficient of active switch and output diode, their ZVS and ZCS condition in the ON and OFF time and voltage gain. Finally the first converter circuit is simulated in PSpice with the two other converters input voltages and the results are compared.


This paper introduces a modern, transformerless buck-boost dc-dc converter. In this topology, one active switch is used. The proposed buck-boost converter voltage gain is higher compared to the conventional buck-boost converter. With a moderate duty cycle, high voltage gain can be reached. The switch's voltage stress is minimal. As a consequence, the power switch's conduction loss is relatively low to improve efficiency. The converter is simple, hence it will be easy to control the proposed converter.
