This paper presents the development, analysis, and performance evaluation of a new topology for an isolated dc power electronic converter (PEC). The proposed topology (called the reverse fly-back dc PEC) is developed to process a discontinuous input voltage and produce a continuous output voltage. The reverse fly-back dc PEC is operated based on charging the inductive element in the high-frequency transformer, while discharging the energy to the output side through On-Off actions of the switching element, which is located on the secondary side of the high-frequency transformer. The proposed reverse fly-back dc PEC is tested for its performance under different operating conditions. Performance results show that the reverse fly-back dc PEC is capable of processing discontinuous input voltages with different duty ratios, and maintain continuous output voltages with a minor sensitivity to the load type of ratings.
