iMOTION™ Modular Application Design Kit

Hardware description of EVAL-M3-102T

5.2

PFC Hardware configuration

5.2.1

PFC Topology selection

The EVAL-M3-102T control board applies to both of PFC algorithms, boost mode and totem pole. The user

needs to make sure that the topology configuration matches with power board hardware configuration. The

topology configuration can be changed in MCEWizard by clicking and selecting in the pull down list marked

with red box as shown in Figure 16.

Figure 16 The PFC topology choose in MCEWizard for EVAL-M3-102T and EVAL-M3-CM615PN

5.2.2

PFC External Current feedback configuration and calculation

Please refer to the schematic diagram of power board for the shunt resistance value (For example, the shunt

resistors are 30mΩ for EVAL-M3-CM615PN and 100mΩ for EVAL-M3-TS6-606).

The current input value is product of the shunt resistance in milliohms and gain of External current sense

amplifier as shown in Figure 17.
