Analytical expressions describing the input current spectrum of the flyback Pulse-Width-Modulated,
Zero-Current-Switched Quasi-Resonant-Converter, and Zero-Voltage-Switched
Quasi-Resonant-Converter are derived in terms of normalized circuit parameters. These analytical
results are tested against experimental results. The same numerical example is presented
for these three converters in which the input current spectrum is computed for various
line/load conditions and the results are mutually compared. Detailed experimental results are
presented for the same three converters as well as for the flyback Zero-Voltage-Switched
Multi-Resonant-Converter. The effects of any parasitic oscillations in the experimental circuit
are also considered.
