POWER MODULE STAGE
The fast-in connectors PFC_OUT “+” and PFC_OUT “-” provide DC bus voltage to the
Power Module Stage. The recommended cable size is 16-18 AWG or 1.0 to 1.5mm
is also recommended that cables used for the power connections should be terminated
with blue or red crimp terminals. If crimp terminals are not used, care should be taken
to ensure that stray strands of wire do not short to adjacent terminals or the enclosure.
If possible, all wires should be stripped and tinned with solder before connecting to the
dsPICDEM MCHV development board terminals.
The 14-pin keyed connector provides the signals and power supply rails from and to
the Power Stage. These signals are shown in Table 4-1.
TABLE 4-1:
This board has two main functions; the first is to control the motor using a dsPIC DSC
and a Power Module and the associated feedback signals for each control algorithm.
The second is to provide the safety means to interact with the user.
4.2.1
This section summarizes the resistor configuration required to connect the PIM pins to
dsPIC DSC pins. The following PIMs can be configured on the dsPICDEM™ MCHV
Development System:
• dsPIC33FJ256MC710 PIM (MA330013)
• dsPIC33FJ12MC202 PIM (MA330014)
• dsPIC33FJ32MC204 PIM (MA330017)
• dsPIC33FJ128MC804 PIM (MA330018)

Plug-In Module Configuration
The user should only access the power terminals when the system is fully
discharged (see the “Safety Notice” on page iii).
The circuits for the hardware described in this section are shown in
Appendix A. “Board Layout and Schematics”.
When using PIMs, make sure that the 28-pin SOIC dsPIC DSC is removed
from the dsPICDEM™ MCHV Development System.
