Switching Converter, SMPS Transformers

Switching Converter, SMPS Transformers are used to construct switch mode power supplies (SMPS) which are a type of power supply that uses semiconductor switching techniques rather than standard linear methods to provide the required output voltage. The basic switching converter consists of a power switching stage and a control circuit that may be designed to work with specific chipsets.
