7.3.2 Selecting Current Sensing Shunt Resistor
N side DC-link is detected and the protective operation signal is passed through the RC filter. If the current
exceeds the SC reference level, all the gates of the N-side three-phase IGBTs are switched to the OFF state
and the Fo fault signal is transmitted to the CPU. Since SC protection is non-repetitive, IGBT operation
should be immediately halted when the Fo fault signal is given.
to the reference SC trip voltage in the LVIC. The drive IC then interrupts low-side IGBT gates to stop IGBT
operation. The value of current sensing resistor is calculated by the following expression:
