6.3 Recommended Wiring of Shunt Resistor and Snubber Capacitor
patterns between the shunt resistors and SPM will cause excessive surges that might damage the Mini DIP
SPM ’s internal ICs and current detection components, and may also distort the sensing signals. To decrease
the pattern inductance, the wiring between the shunt resistors and SPM should be as short as possible.
surge voltages effectively.
installed in the wrong location ‘A’ as shown in the Fig. 6.4, the snubber capacitor cannot suppress the surge
voltage effectively. If the capacitor is installed in the location ‘B’, the charging and discharging currents
generated by wiring inductance and the snubber capacitor will appear on the shunt resistor. This will impact
the current sensing signal and the SC protection level will be somewhat lower than the calculated design
value. The “B” position surge suppression effect is greater than the location ‘A’ or ‘C’. The ‘C’ position is a
reasonable compromise with better suppression than in location ‘A’ without impacting the current sensing
signal accuracy. For this reason, the location ‘C’ is generally used.
