(Equivalent to the inductance of a copper pattern with length = 17mm and width = 3mm.) NU, NV, NW should be connected near terminals. RSHUNT GND wiring from VNC should be as close to the shunt resistors as possible. DRIVE CIRCUIT DIPIPM DRIVE CIRCUIT PROTECTION CIRCUIT NU SHUNT RESISTORS COMPARATORS (Open Collector Output Type) OR OUTPUT NV NW W V U P P-SIDE IGBTs N-SIDE IGBTs VNC Rf Cf Vref − + 5V CIN A C D B Rf Cf Vref − + Rf Cf Vref − + Notes: 1) It is necessary to set the time constraint Rf, Cf of external comparator input so that the IGBT stops within 2 s when short circuit occurs. SC interrupting time can vary with the wiring pattern, comparator speed and so on. 2) The threshold voltage Vref should be set up as the same rating as the short circuit trip level (VSC(ref), typically 0.48V). 3) Select the external shunt resistance so that the SC trip-level is less than specified value (≤1.7 times current rating). 4) Wiring A, B, and C should be as short as possible to avoid a malfunction. 5) Where the wiring to the comparator is divided, point D, should be near the shunt resistor terminal. 6) OR output high level should be over 0.53V (= maximum VSC(ref)). |
