Title:
A SIMPLIFIED CURRENT SHARE CIRCUIT
Document Type and Number:
WIPO Patent Application WO2001033689
Kind Code:
A3
Abstract:
A current sharing circuit scheme comprising first and second power modules (36, 38) each including an input side (30) and an output side (32), the power modules (36, 38) coupled to each other via respective input sides (30), each of the output sides (32) including a positive terminal and a negative terminal. The circuit scheme also comprises first and second circuit output voltage terminals (47, 46) and first and second set point controls (40, 41 coupled to the negative terminal of each of the output sides (32). First and second initial set point control (42, 45) are included providing current signal paths between corresponding first and second set point controls (40, 41) and the first output voltage terminal (47). The first and second set point controls (40, 41) and the first and second initial set point controls (42, 45) are configured to allow current sharing through said first and second output voltage terminal (20) when a current signal is applied to said input side (30) of said first and second power modules (36, 38).
