Abstract (en)

[origin: DE19916686A1] Input circuits (21,22) are connected to AC input terminals (17,18) connected to power supply line (L1) via switches. A discharge circuit (23) is connected between the AC input terminals. The discharge resistance (RC) is less than input resistance (Re). The discharge circuit has a series circuit of rectifier (d), discharge resistance (Re) and transistor (S3).
