Control unit for electric arc lamp with supply part with constant regulated output at its output connections with series inductance in series with lamp and pre-connected HF pulsed switch

摘要

The control unit for an electric arc lamp (14) is designed so that for the detection of the actual power (Pist), an averaged output signal of a current sensor (16) detecting the current pulse (20), produced by the high frequency pulsed switch (11) is formed and supplied to the control circuit (18,19,22,15).
