PCS100 AVC-20 User Manual 27
5.1.1 PCS100 Rectifier Module
The PCS100 Rectifier Modules convert the incoming three phase AC voltage into a regulated DC voltage.
The rectifier modules include a sine filter as part of the assembly, meaning the power electronics and sine filter
are integrated into one module. Based on state-of-the-art IGBT technology and with integrated sine filters
rectifier modules have minimum impact on power quality of the supply network (harmonics and power factor).

5.1.2 PCS100 Inverter Module
The PCS100 Inverter Modules are IGBT based modules that can deliver 150 A continuously. Due to the technology
used the PCS100 AVC-20 can respond within milliseconds to power disturbance events with precise control over
the compensating voltage. Based on state-of-the-art IGBT technology and with integrated sine filters and RFI
filters inverter modules have minimum impact on power quality of the load.
A Fail-Safe Bypass circuit is included in the each PCS100 AVC-20 inverter module. The Fail-Safe Bypass circuit is
designed to remove the inverter from the circuit during overload or manual bypass operating modes, by shunting
the series transformer in the PCS100 AVC-20.
