“…For example, PDM for a three-phase cycloconverter was analyzed, modeled, and simulated in [4]. Others such as [5], [6] and [7] made revisions to the threephase PDM cycloconverter, such as using various resonant converters as the input to the cycloconverter. Additional variant on the soft cycloconverter was reported in [1] which uses an isolated input to the cycloconverter.…”

Abstract-Single stage cycloconverters generally incorporate hard-switching at turn on and soft-switching at turn off which limit limits their use in lower frequency applications. This paper presents a proposed solution to this problem using a pulse density modulated soft-switching cycloconverter or abbreviated PDMSS cycloconverter. Unlike standard cycloconverters, the controller in PDMSS cycloconverter lets only complete half cycles of the input waveform through to the output. This requires a much greater frequency step down from the input to the output. The analysis and design of the PDMSS cycloconverter will be described using a simulink model whose results demonstrate the ability of PDMSS to produce the sinusoidal waveforms.

This thesis explores the analysis and design of a pulse density modulated (PDM), soft switching cycloconverter. Unlike standard cycloconverters, the controller in this converter does not adjust thyristor firing angles. It lets only complete half cycles of the input waveform through to the output. This allows and requires a much greater frequency step down from the input to the output. The advantages, shortcomings and tradeoffs of this topology are explored as this converter is designed, built and tested.The resulting cycloconverter has many deficiencies, but proves the concept of the PDM soft switching technique. Cases for further improvement and study are outlined. In the end, this converter shows much promise for applications requiring a high step down in frequency, as well as where the lower electromagnetic interference (EMI) of soft switching may be beneficial.v
