Abstract

The present invention involves a parallel double resonant power supply (20') for a gas filled discharge lamp (22, 22'). The control section (32') provides input undervoltage lockout, excess primary voltage lockout, and major output current imbalance lockout functions which de-energize power supply in the event of faulty operating conditions being sensed.
