21 / 41 page ![]() User Manual 21 of 41 Revision 1.4 2019-10-11 EVAL-M3-CM615PN User Manual iMOTION™ Modular Application Design Kit Hardware description of EVAL-M3-CM615PN Figure 17 The PFCTRIPREF Circuit on the EVAL-M3-102T evaluation board The PFC’s overcurrent protection circuit on the control board EVAL-M3-102T is shown in Figure 15 and Figure 17. The IPFCTRIP_Peak equal to 6.88A for the combination between EVAL-M3-102T and EVAL-M3-CM615PN only. The calculation formula is as follows, =( ∗ − ∗ )∗ ( + )∗ ∗ If larger PFC current protection setting value needed, please use smaller resistance of PFC shunt resistor RS1, or modify the control board EVAL-M3-102T following the previous formula. Please refer to the control board’s user manual for more details. 5.2 Inverter section using CIPOS™ mini IPM The inverter section is also implemented using the CIPOS™ mini IPM as sketched in Figure 18. The inverter section of IPM module includes an optimized SOI gate driver and a three-phase inverter consisting of TRENCHSTOP™ IGBTs and anti parallel diodes. The three pairs of capacitors C11 and C12, C13 and C14, C15 and C16 are used as bootstrap capacitors to provide the necessary floating supply voltages VBS1, VBS2 and VBS3 respectively. 3.3V PFCTRIPREF IPFC0 iMOTION Controller 12 IPFC PFCTRIPREF 21 |
