Hardware description of EVAL-M3-IM564
There are two AC voltage sensing modes in MCEWizard, differential mode and single-ended as shown in Figure
12. Please select differential mode for the combination between EVAL-M3-IM564 and EVAL-M3-102T.

The high side resistors R1 and R2 or R9 and R10 for the AC voltage sensing resistor divider on the power board
EVAL-M3-IM564 is 2000kΩ, and should be configured in MCEWizard as shown in Figure 13. For the low side
resistor value, please refer to the User Manual of the corresponding control board.

Hardware Modification for AC Voltage sensing to work with IRMCF188
As mentioned in the previous setion, AC voltage sensing is in the front of rectifier bridge D1 by default for this
power board EVAL-M3-IM564 as shown in Figure 10. But for control board EVAL-M3-188 with controller IC
