System Description
The IRPT2051C powIRTRAIN provides the complete power conversion function for a 3hp (2.2kW) variable-frequency, variable-voltage, AC motor controller. The powIRTRAIN combines a power assembly IRPT2051A with a Driver-Plus Board IRPT2051D. Figure 1 shows the block diagram of the powIRTRAIN within an AC motor control system.
