Title:
ELECTRONIC TRANSFORMER FOR LIGHTING
Document Type and Number:
WIPO Patent Application WO2000028792
Kind Code:
A3
Abstract:
An electronic transformer (10) for lighting inlcudes a rectifier (13) coupled to an inverter (18, C2, C3, Q1, Q2) an output transformer (T1, T10) and a drive transformer (T2, T11). A protection mechanism (VR1, VR2) is responsively coupled to a winding of the output transformer and to a winding of the drive transformer such that the voltage across each of the windings are approximately equal and opposite during normal operation but differ substantially during a short-circuit.
