Symmetry Control Circuit And Method

US Patent:
5583402, Dec 10, 1996
Filed:
Jan 31, 1994
Appl. No.:
8/190746
Inventors:
Mihail S. Moisin - Lake Forest IL
Bryce L. Hesterman - Fort Wayne IN
Antonio Marques - Hattiesburg MS
Allan A. Nostwick - Huntington IN
Assignee:
MagneTek, Inc. - Nashville TN
International Classification:
G05F 100
US Classification:
315307
Abstract:
The present invention provides a method and circuit for controlling the flow of current through a load. In a preferred embodiment, an oscillator generates a pulse signal of constant frequency. A pulse width modulator adjusts the duty cycle of the pulse signal in response to a dimming level signal input indicative of the desired level of current flow through the load. A converter receives the pulse signal as an input and converts it into an AC signal, the frequency of which follows the frequency of the pulse signal and the symmetry of which varies with the duty cycle of the pulse signal. The load is connected into a resonant circuit tuned such that a change in the symmetry of the AC signal changes the level of current flowing through the load.
