摘要： There is disclosed a power conversion circuit including self synchronous rectifiers and a rapid shutdown section. When power is removed from the power conversion circuit, the rapid shutdown section prevents self oscillation of the self synchronous rectifiers. As a result, power is not drawn from the output and dissipated in the power conversion circuit.

摘要： A portable electric power supply with a main contactor relay connected in electrical series with a manual safety switch and voltage sensing relay contactor between the neutral conductor and a power conductor of the power supply. A voltage sensing relay detects the voltages in the power supply and turns on the voltage sensing relay contactor when the voltages reach a minimum value. The safety switch is wired in parallel with a latching contactor. The main contactor relay activates a main power contactor and the latching contactor when the voltage sensing relay contactor and one or both of the safety switch and latching contactor are activated, and deactivates the main power contactor and latching contactor when the voltage sensing relay contactor is deactivated. When activated, the main power contactor connects power outlets to the neutral conductor and power conductors.

摘要： A control circuit for preventing equipment from being damaged by voltage sag uses a modular circuit having a rectifier, an electricity storing device or a control relay to perform functions of charging, discharging, and controlling. The modular circuit can be applied to control circuits of all equipment for increasing stability of the equipment. When a power source of the control circuit has voltage sag, the electricity storing device discharges for assisting a winding of a magnetic switch in riding through a temporary period of demagnetization. Consequently, the main connections keep contact for preventing the power source from being broken and also preventing the equipment from being damaged.

摘要： A method and apparatus for enabling a processor to execute processing routine even if a power-source voltage drop occurs during processing. When an ignition key switch 102 is closed, voltage VB is supplied from a vehicle-mounted battery B1 to a comparator AMP of a CPU 108 and to a power-source stabilizer circuit 201 of a regulator 200. Also, capacitors C1 and C2 are charged with a load from the vehicle-mounted battery B1. Even if the power-source line is momentarily interrupted while in this state, the capacitor C1 has already been charged, and so the transition of the drop in voltage VB is gradual compared with a case wherein the capacitor C1 is absent. Additionally, because the capacitor C2 has already been charged, voltage VCC supplied to the CPU 108 from the regulator 200 is held at a fixed value for a certain interval. Because of this, the drop in voltage VCC is delayed and the power source is switched from the vehicle-mounted battery B1 to a battery B2, thereby allowing the CPU 108 to continue to perform uninterrupted data processing.
摘要翻译：即使在处理期间发生电源电压下降，也能够使处理器执行处理程序的方法和装置。当点火钥匙开关102闭合时，电压VB从车载电池B1供给到CPU108的比较器AMP和调节器200的电源稳定器电路201。而且，电容器C1和C2被充电来自车载电池B1的负载。即使在该状态下电源线短暂中断，电容器C1已经被充电，因此与不存在电容器C1的情况相比，电压VB的下降的转变是逐渐的。此外，由于电容器C2已经被充电，所以从稳压器200提供给CPU108的电压VCC被保持在固定值一定的间隔。因此，电压VCC的下降被延迟并且电源从车载电池B1切换到电池B2，从而允许CPU 108继续执行不间断的数据处理。

摘要： A motor controller for a battery-powered electric motor automatically disables the motor when the battery voltage (1) remains below a first, higher level for a longer time when the motor is off, or (2) remains below a second, lower level for a longer time when the motor is on, or (3) falls below a low level less than about one quarter the nominal level of the voltage for a shorter time. The motor is automatically enabled when the battery voltage rises to a higher level for a preset time period, indicative of charging of the battery.

摘要： A power supply system (300) provides a staged startup of multiple loads (303, 305). Preferably, the power supply (300) is a switching power supply that provides power, in the form of a primary output voltage to a first output terminal (319) and to a second output terminal (325). A first load (303) demands a first startup power from the switching power supply through the first output terminal (319). A voltage comparator (333) provides an enable signal (335) when a primary output signal, present at the first output terminal, exceeds a predetermined threshold (335). A load coupling device, preferably a gateable voltage regulator (331), is coupled to the second output terminal (325). The gateable voltage regulator (331) has an output (327) coupled to a second load (305). The gateable voltage regulator (331), responsive to the enable signal (335), provides a coupling between the second output terminal (325) and the second load (305), whereby the second load (305) demands a second startup power from the power supply through the second output terminal (325).

摘要： A digital voltage detector uses a running average to detect utility service disturbances in real time. An isolation transformer taps the main electrical AC power supply line and provides an analog voltage waveform to a system controller. The analog waveform is sampled digitally in real time, and the samples are squared to create respective instantaneous squared voltage values. A running average is kept of the instantaneous squared voltage values for a preselected period of time, preferably one half-cycle for the main power supply waveform. The running average is compared to a preselected under-voltage threshold value and a preselected over-voltage threshold value, and a disturbance detection signal is generated if the running average violates either threshold value. The disturbance detection signal is preferably used to activate a standby electrical AC power supply, and contemporaneously to disable the main electric AC power supply.
