inverter. A thermistor is included in the inverter section for thermal
sensing.
The power stage is designed to minimize inductance in the
power path and reduce noise during inverter operation. The
power level interfaces to the Driver-
Plus
Board through solder
pins, minimizing assembly and alignment. The power assembly
mounts to a heat sink with five screw mount positions, one in
each corner and a fifth near the center to insure good thermal
contact between the IMS and the heat sink. Wide copper traces
on the IMS insure low impedance interconnects for the power
components.

provides detailed functional block diagrams of the IRPT5051D.
The
switching power supply
delivers a nominal 18V DC out-
put, referenced to the negative DC bus, N. This feeds the gate
drive, relay control and under voltage (UV) circuits, which are opti-
cally isolated from the control input section, and therefore require
their own local power source.
The
gate drive circuits
deliver on/off gate drive signals to the
IGBTs' gates, corresponding with input PWM control signals IN1
through IN6.
The
PWM gate
normally allows the input PWM control sig-
nals to pass to the input opto-isolators of the gate drive circuits.
The conduction periods of the inverter switches essentially mimic
those demanded by the PWM input signals.
During power-up and power-down, or in the event of overcur-
rent (OI) or overtemperature (OT), the
latch
inhibits the PWM
System Description
The IRPT5051C
POW
IR
TRAIN
provides the complete power
conversion function for a 15hp (11kW) variable frequency AC mo-
tor controller. It contains a 3-phase input rectifier, DC link capacitor,
3-phase IGBT inverter, isolated gate drive circuits, shutdown protec-
tion, isolated trip and current feedback signals, and capacitor
pre-charge function. Terminal blocks fitted to the
POW
IR
TRAIN
allow for end-user input and output connections.
Output power is pulse-width modulated (PWM) 3-phase, vari-
able frequency, variable voltage controlled by externally
generated user-provided PWM logic input signals, which control
the inverter stage – IGBT switching. The PWM input signal ter-
minals and the output feedback signals are optically isolated from
the power circuit.

within an AC motor control system. Figure 4 shows the functions
and architecture of the IRPT5051C.
The IRPT5051C combines a lower Insulated Metal Substrate
(IMS) power board, containing the power semiconductors and a
thermistor, with the Driver-Plus Board. The power assembly is
designed to be mounted to a heat sink. Figure 2 shows the
IRPT5051A power assembly.
The Driver-
Plus
Board interfaces electrically to the IRPT5051A
power assembly via soldered connector pins. All external connec-
tions to the
POW
IR
TRAIN
are made to terminal blocks on the
Driver-
Plus
Board (figure 3.)
The IRPT5051C
POWIRTRAIN
offers several benefits to the
motor control manufacturer:
·
It eliminates component selection, design layout, intercon-
nection, gate drive, local power supply, thermal sensing,
current sensing, and protection.
·
It provides committed power semiconductor losses and
junction temperatures.
·
Parts inventory is reduced.
·
Gate drive and protection circuits are designed to closely
match the operating characteristics of the power semiconduc-
tors. This allows power losses to be minimized and power
rating to be maximized to a greater extent than is possible by
designing with individual components.
·
Optimized layout for performance and efficiency is pro-
vided.
·
Low inductance system reduces noise and snubber require-
ments.
·
Manufacturing assembly is greatly simplified.
