Hardware description of EVAL-M3-CM615PN

To meet individual customer requirements and make the Eval-M3-CM615PN evaluation board a basis for

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

included in this chapter.

5.1

Boost PFC section using CIPOS™ mini IPM

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

circuitry includes a passive EMI filter consisting of elements CX1, CX2, L1, CY1 and CY2, a 25 A/600 V rectifier

bridge U1, a fuse F1 for inrush current protection, a NTC resistor RT1 and a relay RLY1 for soft powering up and

sketched in Figure 10. The IRS44273L is used to drive IGBT for PFC section. A PFC inductor should be connected

to J2. PFC inductor is included in this evaluation kit.

Figure 10 Schematic for EMI filter and PFC section of the Eval-M3-CM615PN evaluation board

The PFC section of CIPOS™ IPM IFCM15P60GD contains a TRENCHSTOP™ 5 IGBT and a rapid switching emitter

controlled diode. The PFC IGBT’s anti-parallel diode D3 is mandatory. For 650W power output, the inductance

of PFC inductor should be larger than 3mH. Two electrolytic capacitors E1 and E2 are used for buffering the

rectified DC bus voltage DCP.

5.1.1

AC Voltage sensing and MCEWizard configuration

AC voltage sensing is in the front of rectifier bridge U1 by default as shown in Figure 10. To dive the boost PFC

circuitry for EVAL-M3-CM615PN, the default matching MADK control board is EVAL-M3-102T. Figure 11 shows

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