Analysis of tunnel-diode converter performance

Three tunnel-diode converter circuits-the Storm and Shattuck circuit, a push-pull version, and the Marzolf circuit-are analyzed graphically to obtain waveforms for both inverter and dc converter operation. Simple expressions are found for diode efficiency in ideal dc converter operation. The efficiencies are the same except that the efficiency of the Marzolf circuit is reduced by the magnetizing current required for the square-loop core. However, the Marzolf circuit has a more nearly square waveform and would require less filtering for dc conversion. The results point up the importance of developing tunnel diodes with high peak-to-valley ratios for converter application.
