摘要： A motor drive circuit for use in driving a motor having two or more phases comprising a motor bridge having, for each phase of the motor, a bridge arm comprising an upper switch and a lower switch that in normal operation may be opened and closed to modulate the voltage applied to the respective phases in response to drive signals from a motor control circuit, at least one solid state phase isolation relay that is provided in series in an electrical path connecting a respective phase of the motor to a respective bridge arm, the relay being closed in normal operation so that current can flow in the phase and is held open in a fault mode of operation to prevent the flow of current in the phase. The circuit also includes monitoring means for monitoring the current waveform in the phase to provide, at least in a fault mode of operation, an output indicative of when it is safe to open the SSPIR without causing damage due to the SSPIR due to an avalanche mode, and a control circuit that during normal operation applies a voltage to each device that is sufficient to hold the SSPIR closed and which, in the fault mode of operation, responds to the output of the monitoring means to reduce the voltage applied to each SSPIR to a level that causes the SSPIR to open at the safe time.

摘要： A chopper device includes: a series circuit connecting at one end to a positive pole of a DC power source and having a breaker and a reactor; a series circuit connected between another end of the stated series circuit and a negative pole of the DC power source and having switches; a series circuit connected in parallel to the switch and having a diode and a capacitor; and a series circuit connected in parallel to the switch and having a diode and a capacitor. The chopper device outputs a DC voltage at three potentials from both ends and a midpoint of a series circuit having the capacitors by turning the switches ON/OFF. The chopper device further includes other switches connected in parallel to the switches. When a short-circuit fault is presumed to have occurred in the switch, the other switch is turned ON before interruption is performed by the breaker.

摘要： A power supply current monitoring device is used for a load drive apparatus with two systems to drive a load. Each system includes a drive circuit connected in parallel with a battery, a capacitor connected between the battery and the drive circuit, and a relay connected between the drive circuit and a point at which power of the battery is divided between the systems. When overcurrent is detected once in one system, a repetitive monitoring process is performed. The monitoring process finally determines that the overcurrent actually occurs when a predetermined condition is satisfied after repeating a monitoring cycle in which an overcurrent time during which the overcurrent continues after the relay is turned ON is accumulated. The condition is satisfied when the monitoring cycle in which the overcurrent time reaches a predetermined threshold is repeated a predetermined consecutive number of times.
