Abstract: A high-speed charger with a long lifespan such that a power converting inverter can be reliably stopped in accordance with a forced stop signal, without causing a malfunction. Pulse transformers corresponding respectively to switching elements configure an inverter. A control circuit outputs gate signals for switching on and off the switching elements to primary side circuits, each of which includes a primary winding of one of the pulse transformers. Gate drive circuits switch on and off of the switching elements based on voltage generated in secondary windings of the pulse transformers. Transistors acting as interruption control switching elements are interposed in the primary side circuit of each of the pulse transformers. The transistors are cut off in accordance with a forced stop signal, whereby an operation of the inverter stops.

Abstract: A charger with a power converting inverter that can be reliably stopped by a forced stop signal, without causing an increase in part quantity. A control power supply supplies voltage to gate drive circuits, which supply gate signals to an inverter. The control power supply includes a transformer, a power supply control circuit IC that repeatedly opens and closes a primary side circuit formed by a primary winding of the transformer and an auxiliary machine power supply being connected in series, and a rectifier that generates power supply voltage to be supplied to the gate drive circuits by rectifying AC voltage generated in a secondary winding of the transformer. The power supply control IC turns off a FET in accordance with a forced stop signal, thereby forcibly switching the primary side circuit to an open state, and stopping the supply of power supply voltage to the gate drive circuits.

Abstract: A charger, in one possible configuration, has an AC/DC converter that converts alternating current power supplied from an external alternating current power supply into direct current power and outputs the direct current power, a DC/DC converter that transforms the direct current power output by the AC/DC converter and supplies the transformed direct current power to a vehicle-mounted battery, and a safety control unit that forcibly stops the DC/DC converter with detection of an occurrence of a fault during charging of the vehicle-mounted battery as a trigger, and subsequently causes the AC/DC converter to stop normally.

Abstract: First and second detectors and first and second forced stop circuits are included in a charger including an AC/DC converter having a PFC circuit that converts AC power supplied from an external AC power supply into DC power and a smoothing capacitor, and a DC/DC converter that transforms power output by the AC/DC converter and supplies the transformed power to a vehicle-mounted battery. The first and second detectors detect voltage applied to the vehicle-mounted battery. The first forced stopper determines whether or not voltage detected by the first detector exceeds a predetermined threshold, and causes the DC/DC converter to stop when the predetermined threshold is exceeded. The second forced stopper determines whether or not voltage detected by the second detector exceeds the threshold, and causes the DC/DC converter to stop when the threshold is exceeded.

Abstract: An electric parking brake device holds a parking brake in a braking state by a rotation-linear motion conversion mechanism that converts rotation of an electric motor into a motion in a linear direction, and releases the parking brake by the rotation-linear motion conversion mechanism. In a case of releasing the parking brake, the electric motor is controlled by combining PWM control and ON/OFF control with each other. When the electric motor is driven according to the PWM control, and a predetermined time has elapsed after start of the PWM control, then the electric motor is changed to drive according to the ON/OFF control. In the ON/OFF control, a change in which a drive current of the electric motor is decreased stepwise is detected, whereby a torque drop of the rotation-linear motion conversion mechanism is detected.

Abstract: In a charger, according to one possible configuration, a pulse signal from a DC/DC converter control unit and a signal from a main safety control unit are applied to a mask. The mask outputs a result of an AND operation on the signals to a gate drive unit and a checking unit. The main safety control unit temporarily changes the output signal from an H level to an L level at a predetermined timing in a state where no information indicating a fault of the charging operation is acquired, and holds the output signal for a predetermined time. When a pulse signal is output without the output of the mask switching to an L level during this time, the checking unit outputs an H level signal. When acquiring the H level signal from the checking unit, the main safety control unit determines that the mask is not operating normally.
