Zero-voltage-switched multi-resonant converters including the buck and forward type
(United States Patent and Trademark Office, 1989-08-15)
A multi-resonant-switching network that operates under switching conditions that are favorable to both the active switch and the diode that constitute the switch. In a zero-current multi-resonant switch, the resonant circuit ...
Non-destructive tester for transistors
(United States Patent and Trademark Office, 1989-07-25)
A non-destructive reverse-bias second breakdown tester for testing semiconductor devices such as transistors and thyristors that have a base-collector-emitter configuration. The tester basically comprises a socket for ...
Half-bridge zero-voltage switched multi-resonant converters
(United States Patent and Trademark Office, 1989-08-22)
A half-bridge zero-voltage-switched multi-resonant converter. The converter basically comprises a device for converting an input voltage signal to a DC output signal to be imposed across a load. The device includes input ...
Multi-loop control for quasi-resonant converters
(United States Patent and Trademark Office, 1989-09-12)
A multi-loop controller for controlling a quasi-resonant converter having a power switch, a filter inductor and an output voltage. The controller includes a sensor circuit for sensing the output voltage of the converter. ...
