摘要
Low-voltage outputs are provided by full-bridge rectification using controlled switches with fault detection monitoring of circuit conditions and disabling switches upon detection of a fault to decouple the converter from the system. Common-source dual MOSFET devices include elements arranged in alternating patterns on the die. Common-source dual synchronous rectifiers include control circuitry powered from the voltage across the complementary switch. A DC-to-DC transformer converts power using a fixed voltage transformation ratio. A clamp phase may be used to reduce power losses, control the output resistance, effectively regulate the voltage transformation ratio, provide narrow band output regulation, and control the rate of change of output voltage. A new point of load converter includes input driver circuitry removed from and output circuitry located at the point of load, with a transformer located near the output circuit and an AC bus between the driver circuit and the primary winding of the transformer.
