    摘要： The present invention provides a discharge handling system capable of appropriately handling occurrence of an arc discharge according to a situation. A discharge handling system includes: a power module; a power conversion device; and an arc discharge detection device, the arc discharge detection device including an arc discharge detector configured to detect occurrence of an arc discharge between the power module and the power conversion device, the arc discharge detection device monitoring the number of times of the arc discharge detected by the arc discharge detector and discharge time of the arc discharge every time a monitoring time elapses. The discharge handling system includes a determination unit configured to determine necessity of maintenance within a predetermined period on condition that any of conditions (1) to (3) below is satisfied: (1) the number of times of the arc discharge in the monitoring time is from 1 to a number-of-times threshold inclusive; (2) each of the discharge time of the arc discharge in the monitoring time is equal to first determination time or less; and (3) total of the discharge time of the arc discharge in the monitoring time is equal to second determination time or less.

    摘要： A current sensing module (100) includes a shunt resistor (10) for receiving and sensing a current (Ib), a digital sensing circuit (20), and an analog sensing circuit (30) . The shunt resistor (10) includes a connecting part (10C), a first resistive part (10A) and a second resistive part (10B) coupled in series to the first resistive part (10A) via the connecting part (10C). The digital sensing circuit (20) measures a first analog voltage (V1) of the first resistive part (10A) when the current (Ib) flows through the first resistive part (10A), and provides a first digital measuring value (I1d) associated with the first analog voltage (V1). The analog sensing circuit (30) measures a second analog voltage (V2) of the second resistive part (10B) when the current (Ib) flows through the second resistive part (10B), and provides a second analog measuring value (V2a) associated with the second analog voltage (V2).

    摘要： The present invention relates to a circuit failure detector comprising: an input terminal for receiving a detection signal having a first frequency from an interlock circuit; a correction circuit for correcting the voltage of the received detection signal; a first comparator comparing the corrected detection signal with a first reference voltage and outputting a high voltage signal or a low voltage signal; a second comparator inverting the corrected detection signal, comparing the inverted detection signal with a second reference voltage, and outputting the high voltage signal or the low voltage signal; a counting signal generator for generating a counting signal having a second frequency; a first coupler for coupling an output signal of the first comparator with the counting signal; a second coupler for coupling the output signal of the second comparator with the counting signal; and a controller for detecting a circuit failure on the basis of the output signal of the first coupler and the output signal of the second coupler.
