摘要： A network system includes a network bus structured to power plural network loads. A generator is structured to provide forward power flow to the network bus. A generator protector relay cooperates with the generator. Plural network protectors correspond to plural power source feeders, which are structured to provide forward power flow through corresponding network protectors to the network bus. Each network protector includes a network protector relay having an interface communicating power flow information to a communication network. A controller cooperates with the generator protector relay and includes an interface receiving the power flow information from the communication network and a processor determining whether there is forward power flow through the network protectors to the network bus. The processor enables the generator protector relay responsive to the forward power flow and reduces output from the generator responsive to the forward power flow being less than a predetermined amount.

摘要： In a power converter apparatus, such as an uniterruptible power supply, a phase reference signal is generated responsive to a DC voltage on a DC bus. A magnitude reference signal may be generated responsive to a phase current of an AC bus and/or the DC voltage on the DC bus. Power is transferred between the AC and DC busses responsive to the phase reference signal and the magnitude reference signal. Generation of the phase reference signal may include generating a DC voltage error signal responsive to the DC voltage on the DC bus, generating a phase offset signal responsive to the DC voltage error signal, and generating the phase reference signal responsive to the phase offset signal. Generation of the magnitude reference signal may include generating a volt-amperes reactive (VAR) error signal responsive to the phase current and generating the magnitude reference signal responsive to the VAR error signal.

摘要： A protecting apparatus includes a back-flow preventing Zener diode having a cathode connected directly to a control terminal of a main transistor formed on a semiconductor substrate. A protecting transistor has an output terminal connected to an anode of the back-flow preventing Zener diode and an input terminal connected to an input terminal of the main transistor. A protecting capacitor or Zener diode circuit is connected between a control terminal of the protecting transistor and the input terminal of the main transistor for allowing initial surge current, when caused based on a rapid surge, to flow into the control terminal of the protecting transistor. The protecting transistor, when turning on in response to the initial surge current, allows next surge current succeeding the initial surge current to flow into the control terminal of the main transistor via the back-flow preventing Zener diode. And, the main transistor, when turning on in response to the next surge current, allows late surge current succeeding the next surge current to flow therethrough.

摘要： A short circuit protection circuit for IGBTs and similar power switch devices. Device collector voltage, e.g., desaturation voltage, is monitored to detect rapidly the occurrence of a short circuit fault. The voltage between the power device emitter and the Kelvin emitter terminals of the device preferably is also monitored and integrated to obtain an estimate of the current flowing through the power switch device. Circuit protection is implemented if either the measured collector to emitter voltage exceeds a selected level or the estimated current through the device exceeds a selected level. Upon the detection of the fault, a capacitor in parallel with a zener diode is connected between the power switch gate and ground. Thus, following a fault, the gate voltage is driven quickly to a low level as the voltage on the gate is discharged through the capacitor. The zener diode establishes a clamp voltage at a selected level of gate voltage that permits controlled current flow through the power switching device that is within the capacity of the device so that the device is not damaged. A pre-charged capacitor is then connected between the gate and ground to turn off the power switching device gradually as the pre-charged capacitor discharges into the gate. The voltage level on the pre-charged capacitor is established by a zener diode connected in parallel thereto.

摘要： A power filter circuit for protecting electronic equipment from electromagnetic interference introduced by a supply system circuit includes a fault condition sensing circuit capable of detecting whether the supply system circuit is properly wired. The sensing circuit controls switching circuits in accordance with the determination of whether the supply system is properly wired. The sensing circuit activates a first switching circuit to form a short circuit between the neutral and ground conductors of the power filter circuit when it is determined that the supply system circuit is properly wired. If any wiring fault conditions, including a reverse polarity wiring, is detected by the sensing circuit, the first switch is not activated and the short circuit is not formed between the neutral and ground conductors. The sensing circuit controls a second switching circuit which corrects the polarity when a reverse polarity condition is detected and which does not change the polarity when a correct polarity condition is detected. The sensing circuit can be used with the first and second switching circuits in combination. In this case, the first switching circuit can form a short circuit between the line conductor of the power filter circuit and the ground conductor when a reverse polarity condition is detected to provide superior common mode electromagnetic interference suppression.
