DC-DC converter based on the bipolar boost converter and Dickson voltage multiplier

A novel modification of DC-DC converter with a high voltage ratio is proposed. The converter consists of an input boost converter, bridge commutator and Dickson voltage multiplier. The circuit is characterized by a high voltage gain. An important advantage of the circuit is its practically rigid external characteristic in the continuous current mode (CCM). This is achieved by the absence of active power losses in the process of capacitors' recharging. An additional advantage of the proposed scheme is the low required capacitance of the voltage multiplier capacitors A detailed analysis of the proposed converters has been produced. The results of theoretical analysis are confirmed by the simulation in MATLAB/SIMULINK. Circuit verification has been made in a laboratory prototype with the output power 200W.
