ACS880-907 - regenerative rectifier units

Description
This supply unit is used in regenerative drive systems to convert three-phase AC voltage to DC voltage. The unit consists of R8i and L filter modules. During motoring the input current flows through diodes to the DC bus of the drive system and the supply unit works as a diode bridge. In regeneration, the current flows from the DC bus through the IGBTs to the supply network. The IGBTs are switched to conduct only once during each network voltage cycle. This reduces switching losses and enables high input and output powers of the unit. Unlike with a thyristor bridge, the IGBTs can be switched off at any time which improves reliability.
