| Abstract |
A DC/DC converter suitable for the use of the electric motorcycle is proposed in this paper.
Considering the safety, the power rating, the reliability, and the efficiency of the converter, the circuit
topology based on the DC/DC forward converter is proposed. Operation modes of the proposed
DC/DC converter are introduced and some important voltage and current waveforms of the converter
are also shown. The voltage stress suppression and energy recovery are achieved by using the passive
snubber of the main switch. Two different feedback control strategies for the proposed DC/DC
converter are adopted to compare the performance of the proposed DC/DC converter. Experimental
results of the converter performance under different operation conditions using different control
strategies are presented. Based on the experimental results, the voltage mode control is
recommended. The proposed DC/DC converter can provide a very stable constant output voltage
for the full range of load currents with the maximum efficiency of 90%. The current
experimental results are very useful for the improvement task of the DC/DC converter. |
