A power supply for discharge lamps with balanced resonant circuit

摘要

The circuit for the power supply of discharge lamps (l1,l2) comprises an inverter (1) and a load circuit with a resonant circuit (12) in series with electrodes (5, 5', 9', 9) of at least one lamp (l1, l2) to be inserted into the load circuit. In order to obtain a uniform brightness along the lamp the resonant circuit is balanced.
