dsPICDEM? MCHV
DEVELOPMENT SYSTEM
USER ’S GUIDE
Chapter 4. Hardware
This chapter describes the hardware components of the dsPICDEM? MCHV
Development System.
Topics covered include:
4.1
POWER FACTOR CORRECTION (PFC) STAGE BOARD
This board has two main functions; the first one is to provide the required power sup-
plies to the power module board stage. The second function is to create the power bus
rail that will be used to energize the motor through the power module.
Note:
4.1.1
The circuits for the hardware described in this section are shown in
AC Supply Input
The AC supply input stage of the board consists of the following components,:
? F1 –15A/250 VAC fast acting fuse (only replace with a part of the same rating)
? C1, C2 – Film capacitors to aid in the suppression of AC supply transients and to
also provide a low impedance return path for any currents that flows from the
power device tabs to the heat sink and enclosure due to capacitive coupling
? C3 – Film capacitor to aid in the suppression of AC supply transients.
? R1 – A metal oxide varistor located across the incoming supply lines to suppress
high energy transients.
? L1 – 2.3 mH/15A Choke inductor for suppressing EMI
? C4 – Film capacitor to aid in the suppression of EMI
? C5, C6 – Film capacitors to aid in the suppression of AC supply transients and to
also provide a low impedance return path for any currents that flow from the
power device tabs to the heat sink and enclosure due to capacitive coupling
? R7 – A 1W high-voltage resistor, which acts to discharge C4
? R6 – A resistor with a negative temperature coefficient that acts to limit the surge
of input current that would occur at initial application of power due to the dis-
charged DC bus capacitance. The initial nominal cold resistance is 1 Ohm, which
reduces once current flows and the device heats up.
? BR1 – A single-phase bridge rectifier to convert the incoming AC into DC suitable
for input to the power conditioning stage.
