3-Phase Active Front End Power Module
AFE 33kW – Scalable to 1MW total system power
Description
The AFE333KAC is a non-isolated fully integrated 3-phase active front end power module that is suitable for use as a bidirectional grid connected rectifier in systems for renewable energy, battery chargers, energy storage and general-purpose converters.
The AFE333KAC takes a 3-phase AC input voltage and converts it into a high voltage DC output. It will control the input power factor to a specified level and allows independent control of both active and reactive current or power.
In addition, it supports bidirectional power flow with a seamless transition between delivery of power to and from the AC grid. Furthermore, it offers a choice of different control modes including direct active/reactive power control, direct active/reactive current control and DC output voltage control.
The AFE333KAC offers a large power density with a DC power level of 33kW in a 19” module with a height of only 4RU. Up to 32 units can be paralleled in a master-slave system for a maximum system power level of more than 1MW.
