摘要： A DC power supply provides plural output voltages with respect to a common reference potential by splitting a DC input voltage potential. The input voltage is equally split into dual voltages by the embodiment described. A buffer circuit is provided between a voltage divider network and an output circuit stage coupled to the load. The buffer circuit operates to maintain a reference voltage node in the output stage at a potential substantially equal to the potential at the common node of the voltage divider network. The split voltages appear as independent power supplies to the load coupled to the power supply.

摘要： A charging/discharging circuit is formed of transistors Q1, Q2; resistors R1-R4; and a capacitor C. The series resistors R1, R2 are connected between the power supply line +Vcc and the circuit ground. The series resistors R3, R4 are connected between the line +Vcc and the circuit ground. The collector of NPN transistor Q1 is connected to +Vcc, the base thereof is connected to the junction between R3 and R4, and the emitter thereof is coupled to the junction between R1 and R2. The collector of PNP transistor Q1 is connected to the circuit ground, the base thereof is connected to the junction between R3 and R4, and the emitter thereof is coupled to the junction between R1 and R2. Capacitor C is connected in parallel to R2. The charged voltage of C is used as a reference potential VR for another linear circuit. Suppose that R1=R2, R3=R4 and +Vcc=10 V. When +Vcc rises from 0 V to 10 V but VR does not reach to 5 V, Q1 is forwardly biased so that C is quickly charged by the emitter current of Q1. When +Vcc falls from 10 V to 0 V but VR does not reach 0 V, Q2 is forwardly biased so that C is quickly discharged by the emitter current of Q2. When VR=5 V (stationary state), Q1 and Q2 are both cut-off, so that only small currents flow through the series circuits of R1, R2 and R3, R4. The time constant of (R1.vertline..vertline.R2).C can be made large so that VR is free from ripples of +Vcc.

摘要： A power supply circuit which comprises a first power source terminal for applying a plus voltage and a second power source terminal for applying a minus voltage. A first transistor is inserted between the first power source terminal and a load. A second transistor is inserted between a base of the first transistor and a ground potential and is controlled by the voltages applied to the first and second power source terminals. A capacitor is connected to the second power source and ground potential. A sequence of applying or cutting-off voltages to be applied to the load is predetermined even when a sequence of applying or cutting-off the voltages from said first and second power source terminals becomes erratic.

摘要： A voltage splitter circuit provides a terminal voltage equal to half the voltage impressed across a pair of voltage busses. The voltage at the intermediate terminal may be used to provide two equal, but opposite, voltages between the intermediate terminal and each of the busses. The intermediate terminal is located between the output circuits of two complementary transistors connected across the busses. The transistors are operated by an amplifier driven by a voltage divider. A feedback circuit exists between the intermediate terminal and the input of the amplifier to stabilize the circuit.

摘要： Disclosed in an example embodiment herein is a technique for performing discovery and power budgeting for a power sharing group comprising a plurality of power supply modules configured for sharing power. Data is collected to determine members of the power sharing group, input power and load power for members of the power sharing group. A power budget is determined for members of the power sharing group and the power budget is distributed to members of the power sharing group. Load shedding inputs are calculated in the event that load power exceeds the capacity of the power sharing group.
