Publication number: 20040085790Abstract: Method and apparatus are disclosed for providing a constant voltage, high frequency sinusoidal output across a varying load, using either a single or multiple switch topology operating at constant frequency while maintaining high efficiency over the entire load range. This embodiment is especially suited to applications which require the sinusoidal voltage be held very close to a desired value in the presence of rapid changes in the conductance of the load, even in the sub-microsecond time domain as is common in computer applications and the like and in powering electronics equipment, especially a distributed system and especially a system wherein low voltage at high current is required.Type: ApplicationFiled: June 23, 2003Publication date: May 6, 2004Applicant: Advanced Energy Industries, Inc.Inventors: Robert M.

Patent number: 6590786Abstract: There is provided by this invention novel and unique circuit topology for controlling the delivery of power to de components that is generally comprised of a combination of a free running unregulated AC generator with a synchronous rectifier working at the same switching frequency as the AC generator. The AC generator operates in zero-voltage switching mode, and the synchronous rectifier operates in both zero-voltage and zero-current modes which allows the use of frequency conversion rates up to 10 MHz. Changing the phase of commutation of the synchronous rectifier in reference to that of the AC generator controls the output power. Resonant sinusoidal and pulse gate drivers are used for both the AC generator and the synchronous rectifier. A low loss current combiner is used at the output of the system.Type: GrantFiled: August 7, 2001Date of Patent: July 8, 2003Assignee: Advanced Energy Industries, Inc.Inventor: Gennady G. Gurov
