摘要： A high-voltage relay system for a vehicle is provided. The system includes a relay, a first contact part positioned between a battery and a power converter, a voltage application unit, and a second contact part positioned between the voltage application unit and the ground. A first resistor is connected, at a first end thereof, in series to a second end of the second contact part and connected, at a second end thereof, to the ground. A controller operates the relay in response to an ON/OFF control signal to short-circuit or open the contacts at both ends of the first contact part or the contacts at both ends of the second and determines whether the relay fails based on the type of the ON/OFF control signal and the voltage value between both ends of the first resistor.

摘要： The present disclosure illustrates an electromagnetic relay device and a control method thereof. In the electromagnetic relay device, a control circuit respectively provides driving power to switch on the two electromagnetic relay units disposed adjacent to each other, and then provides the first holding power and the second holding power, lower than the driving power, to the two electromagnetic relay units after the two electromagnetic relay units are switched on, thereby maintaining the two electromagnetic relay units in the switched-on status. When the electromagnetic relay unit receiving the second holding power is tripped because of the environmental factor, the electromagnetic relay unit receiving the second holding power generates and outputs the trip feedback signal to the control circuit, so that the control circuit increases the first holding power upon receipt of the trip feedback signal. The second holding power is lower than or equal to the first holding power.

摘要： The present disclosure discloses an electrical switchgear configured to control an electro-magnet by using the electro-magnet, a critical temperature device, and an electro-magnet control unit without using a bimetal and a mechanical contact. The electro-magnet switches power applied through a power line in response to a flow of control current to a power device connected to a load side. In a critical temperature device, an output current value varies when a temperature of a heating wire, which is connected to the power line, exceeds a critical temperature by supply current flowing to the power device. An electro-magnet control unit, which is realizable with an SCR, allows a flow of control current of the electro-magnet to be generated or cut off in response to the output current value of the critical temperature device.

摘要： A thermal control process for an electronic power device including a multi junction integrated circuit may include defining a first and at least one second groups of junctions, with each group including one first and at least one second junctions, and associating a thermal detector with each group. A first group control may be executed which detects group electric signals representative of the temperature detected by the thermal detectors, processes the group electric signals with reference to a group critical thermal event, identifies a critical group when the corresponding group electric signal detects the critical group thermal event, and generates group deactivating signals suitable for selectively deactivating the first and the at least one second junctions of the identified critical group with respect to the remaining junctions of the integrated circuit.

摘要： A system for reducing the voltage of an AC electrical supply to a load for the purpose of energy efficiency, comprising a transformer and power converter in circuit between an AC electrical supply and a load, and a bypass switch S to cause the transformer to be taken out of circuit and to connect the electrical supply to the load in the event of a sustained overload of the transformer. The system includes means (14) to measure the temperature of the transformer, means (17) to measure the electrical current in the circuit and control means (15) receiving signals from the sensors (14, 17) and to operate bypass switch S to bypass the transformer and allow it to cool. A fuse F2 and thermal cut out device (16) are in circuit with the secondary winding of the transformer as failsafe means to interrupt the supply to the transformer in the event that the bypass switch fails to operate.

摘要： A pressure switch employs a Wheatstone bridge incorporating piezoresistive elements. The output of the bridge is monitored by a control circuit which produces a first control signal when a high pressure is achieved and produces a second control signal when a low pressure is achieved. The output of the control circuit is coupled to the gate electrode of a high current MOSFET device. The drain electrode of the MOSFET is coupled to one terminal of the motor where the other terminal of the motor is coupled to an operating potential. The source electrode of the MOSFET is coupled to ground. When the monitored pressure reaches a high threshold the MOSFET turns off as biased by the control circuit which in turn disables the motor. If the pressure drops, the control circuit detects this and produces the control signal, which activates the motor through the MOSFET. The gate electrode of the high current MOSFET is also connected to a thermal switch, which thermal switch is mounted on the motor housing and closes when the temperature of the motor exceeds a predetermined value. The closure of the thermal switch or the current switch disables the MOSFET and therefore disables the motor avoiding damage to the system.
摘要翻译：压力开关采用带有压阻元件的惠斯通电桥。桥的输出由控制电路监视，当达到高压时产生第一控制信号，并且当达到低压时产生第二控制信号。控制电路的输出耦合到大电流MOSFET器件的栅电极。 MOSFET的漏电极耦合到电动机的一个端子，其中电动机的另一个端子耦合到工作电位。 MOSFET的源电极耦合到地。当监测到的压力达到高阈值时，MOSFET会被控制电路偏置，从而使电机失效。如果压力下降，控制电路会检测到这一点，并产生控制信号，通过MOSFET激活电机。高电流MOSFET的栅电极也连接到热开关，热电开关安装在电动机壳体上，当电动机的温度超过预定值时闭合。热开关或电流开关的闭合会禁用MOSFET，因此禁止电机避免损坏系统。
