ABSTRACT
The Quiet Converter produces a sinusoidal voltage across a parallel resonant tank. The dc output voltage is obtained after rectification and filtering of the sinusoidal secondary voltage. The voltage-fed converter circuit is the most widely-used, converter topology. The most effective method of regulation for a voltage-fed converter is Pulse Width Modulation. In order to incorporate Pulse Width Modulation, or a drive circuit that has inherent dead time that neither transistor is conducting, there must be a means to commutate the current in the series inductor, L1. The sole reason to use the Quiet Converter is because of its inherent low noise. The noise of the Quiet Converter can be reduced even further by adding a primary and a secondary Faraday Shield. When a Faraday Shield is added between the primary and secondary, the transformer must be designed to accommodate the shield.
