Abstract
This paper describes a silicon-controlled rectifier (SCR) dc-to-dc converter. A switching type circuit is employed which controls the power to a load by connecting the dc source to the load and disconnecting it from the load in a cyclical manner. The on to off time ratio is varied to control the average voltage delivered to the load. Either a constant frequency variable pulsewidth mode, or a constant pulsewidth variable frequency mode of operation is used. This means of controlling a dc voltage is a nearly lossless scheme with high efficiency SCR switches.
