System Description
The IRPT1059C POWIRTRAIN provides the complete conversion function for a 1hp (0.75kW) variable frequency, variable voltage, AC motor controller. The POWIRTRAIN combines a power module IRPT1059A with a Driver-Plus Board IRPT1059D. Figure 1 shows the block diagram of the POWIRTRAIN within an AC motor control system.
