System Description

The IRPT1058C POWIRTRAIN provides the complete conversion function for a 0.75 hp (0.56 kW) variable frequency, variable voltage, AC motor controller. The POWIRTRAIN combines a power module IRPT1058A with a Driver-Plus Board IRPT1058D. Figure 1 shows the block diagram of the POWIRTRAIN within an AC motor control system.
