IR2133 Reference Design Kit: 3-Phase 230VAC 3HP Motor Drive
Product Description
The IRMDAC2 Reference Design is a kit of parts
that work together as an evaluation platform for
IR2133 three phase motor control IC and
IRPT2056A power module. User connects three
phase AC, drive signals, motor and hall sensors to
complete the system. Power hook-up is via terminal
blocks and control signals are made using a single
in line header.
How the IR2133 Control IC Adds Value

IRMDAC2 Kit Overview and System Benefits
· When furnished with user-provided logic level control signals, the IRMDAC2 forms a complete reference
design for a 3HP AC motor. Unlike outdated circuits based upon transformer drive or opto-couplers, the
system uses International Rectifier proprietary level-shifting gate drive circuits integrated within the IR2133
Control IC. Separation of gate drive / control and low-voltage circuits from the power module included in the
kit results in a compact, effecient system. The user benfits from immediate hands-on experience and may
customize at will using shematics and circuit ideas as the basis for production designs.
· Gate drive, control and protection circuits are designed to closely match the operating characteristics of the
power semiconductors. This allows power losses to be minimized and power rating to be enhanced to a
greater extent than is possible by designing with individual components.
· Includes Brake Switch and Drive
1. Host PCB Description
The host PCB receives power input from a 3-phase line and control signals provided by the user. In conjuntion
with the power module the result is a flexible power conversion system, primarily designed for interface with a
3HP Motor, however other 3-phase loads may also be applied. The host PCB supports soft-start function which
reduces inrush current by using an NTC thermistor. Surge suppression is implemented using MOV’s as a further
degree of protection. Also on-board is a regulated low voltage power supply to provide bias for the IR2133 and
other low voltage components. When connected to the power module, the unit is fully protected against overcurrent
and ground faults through DC bus voltage and current feedback. Over-temperature is guarded against through
feedback from a thermistor embedded within the power module. A 16-pin single in line header connector is
provided to interface control signals and two terminal blocks connect 3-phase AC inlet and output to the load.
The user provides 5V CMOS / TTL level signals which are then processed by the IR2133 Control IC and
delivered to the power module.
Signals Available to User
In addition to availability of bias supplies derived for the host PCB, signals from the power module circuits and
those derived and processed on the host PCB such as fault status are available to the user. Current feedback
signal from the low side shunt is available on the IFB pin at 0.025V/A. If filtering of this signal is required to
remove noise, a high impedance buffer stage should be inserted between signal and filter. DC bus voltage
feedback is provided on the VFB pin. This reference is been scaled down by a factor of 100 and should be
protected with a high impedance buffer stage.
Fault Behavior.
The system is designed to tolerate overload conditions for one minute. The user should prevent such conditions
persisting beyond this period. In the event of shutdown initiated by ground-fault, overcurrent or over-temperature,
the inverter outputs are terminated and an LED will light to signal this condition. For more information on fault
