Fig2: Block Diagram for a typical motor drive system using power factor correction
Fig 2, illustrates a typical motor drive system running from AC power and various blocks that make up such a
system. All these power/control blocks are present on the TMDSHVMTRPFCKIT board in form of macro blocks.
Below is a list of all the macro blocks names and numbers present on the board and a short description of it's
function, Fig 3, shows the location of these block on the motor control board and a few key connector location.

HVDMC Main Board [Main] – Consists of controlCARD socket, communications(isoCAN) block,
Instrumentation(DAC's), QEP and CAP connection and routing of signals in b/w the macros and to the
control card.

AC-Power Entry [M1] – Takes input AC power from mains/wall power supply and rectifies it. This
rectified voltage can then be used for input of the PFC stage or used to generate the DC bus for the
inverter directly.

Aux Power Supply Module [M2] – This module can take up to 400V input and generate 5V and 15V
DC power. Rectified AC input can directly be connected to this module or output from the PFC stage
cane be used with appropriate jumper settings.

Iso-USB-to-JTAG Macro [M3] – Provided on board isolated JTAG connection through USB to the host.
Can also be used for SCI (isolated) communication for connection with GUI.

PFC-2PhiL Macro [M4] - Two-phase interleaved PFC stage can be used to increase efficiency of
operation.

Inverter2Ph-HV-3shunt Macro [M5] - Three-phase inverter, provides the inverter stage to enable
control of high voltage motors.

DC-PwrEntry Macro [M6] - DC power entry, used to generate the 15V, 5V and 3.3V for the board from
15V DC power supply supplied with the kit.
Nomenclature: To easily find a component let's say a jumper they are referred with their macro number in the
brackets. For example, [M3]-J1 would refer to the jumper J1 located in the macro M3 and [Main]-J1 would refer
to the J1 located on the board outside of the defined macro blocks.
