发明名称 Controlled switches for fault tolerant power converters
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.

主权项 1. A semiconductor device comprising: a first electronic switch having a first control terminal, a first switched terminal, and a first common terminal, a second electronic switch having a second control terminal, a second switched terminal, and a second common terminal, a first control circuit having an input connected to the first switched terminal and the first common terminal and an output connected to the first control terminal, the first control circuit being adapted to turn the first switch ON and OFF in response to a first voltage across the first switched terminal and the first common terminal; the first control circuit having another input connected to the second switched terminal and being further adapted to control the first switch to be OFF while the second switch is ON irrespective of the first voltage; a second control circuit having an input connected to the second switched terminal and the second common terminal and an output connected to the second control terminal, the second control circuit being adapted to turn the second switch ON and OFF in response to a second voltage across the second switched terminal and the second common terminal; the second control circuit having another input connected to the first switched terminal and being further adapted to control the second switch to be OFF while the first switch is ON irrespective of the second voltage; and a package having at least three terminals including one terminal connected to the first switched terminal, another terminal connected to the second switched terminal, and a common terminal connected to the first common terminal and the second common terminal.
