Hardware description of EVAL-M3-IM564

To meet individual customer requirements and make the EVAL-M3-IM564 evaluation board a basis for

development or modification, all necessary technical data like schematics, layout and components are

included in this chapter.

4.1

Boost PFC section using CIPOS™ Mini IPM

Figure 10 depicts the schematic from the AC input connector J1 to the rectified DC bus voltage DCBUS. This

circuitry includes a passive EMI filter consisting of elements X2, Y2 capacitors and common mode inductor, a 25

A/1200 V rectifier bridge D1, a fuse F1 for circuit protection, a PTC resistor PTC1, and a relay RY1 for soft

powering up and reducing conduction losses in steady state. The PFC section is implemented using the CIPOSTM

Mini IPM as sketched in Figure 10. The IRS44273L is used to drive MOSFETs for the PFC section.

Figure 10 Schematic for EMI filter and PFC section of the EVAL-M3-IM564 evaluation board

The PFC section of CIPOS™ IPM IM564-X6D/IM564-X6DS contains a CoolMOS™ power MOSFET and a rapid-

switching, emitter-controlled diode. Two electrolytic capacitors CE1 and CE2 are used for buffering the rectified

DC bus voltage DCBUS.

AC voltage sensing and MCEWizard configuration

AC voltage sensing is by default in front of the D1 rectifier bridge, as shown in Figure 10. To drive the boost PFC

circuitry for EVAL-M3-IM564, the default matching MADK control board is EVAL-M3-102T. Figure 11 shows the

VAC sensing schematic of the EVAL-M3-102T evaluation board.
