摘要

The module has a rectifier bridge circuit (10) comprising thyristors (Tr1-Tr3). An intermediate condenser charging circuit (20) comprises a series circuit that comprises resistors (R1-R3), where the resistors are connected in parallel to the thyristors and diodes (D1-D3). The diodes and the resistors of the series circuit are integrated in separate semiconductor chips that are connected with each other using chip-on-chip technology. The bridge circuit is designed as a half controlled six-pulse bridge circuit or a half controlled two-pulse bridge circuit.
