摘要： En una distribucion para suministrar energía a partir de una fuente de voltaje a.c. que incluye un puente rectificador (D!) y un convertidor (TRI, D5, C4), un medio inductor (L1) se conecta entre una primera terminal de salida sobre el puente rectificador y un circuito de sedimientos de un valle (10) que incluye cuando menos dos capacitores (C1, C2). El convertidor incluye un transformador (TRI) que tiene un devanado primario que junto con un medio de conmutacion controlable (SW1) se incluye con un circuito que se extiende desde una segunda terminal de salida sobre el puente rectificador hacia la union de interconexion entre le medio inductor y el circuito del sedimiento del valle (10). Cuando el valor absoluto del voltaje de la fuente es mayor a o aproximadamente igual al voltaje intermedio más alto que incluye el voltaje a través de cuando menos un capacitador en el circuito del sedimiento del valle, la energía se suministra desde la fuente hacia el medio inductor y hacia el circuito del sedimiento del valle. La energía después se suministra hacia el convertidor desde la fuente a través del medio inductor y en paralelo desde todos los capacitadores (C1, C2) que tienen el voltaje intermedio más alto, en donde la cantidad de la energía de la fuente suministrada depende del voltaje (Vc3) a través de la entrada del convertidor.

摘要： Accurate low-loss regulation of the d-c electrical outputs delivered by each of a plurality of supply channels (26, 26', 27) energized by pulses from a common power source (34) is achieved independently through low-power magnetic-circuit control of important switching effects by which power-gating inductive reactance is efficiently alternated between relatively high and low values. The required switching in each channel (26, 26', 27) results from low-power substantially continuous electrical biasing of the control winding (8 B ) of a saturable reactance (8) by a transistorized network of relatively noncritical and inexpensive construction, which responds to differences between sensed outputs and a reference. Each pulse of power, which is to be gated to the output through the main (8A) winding of the reactance (8) is at first effectively blocked, because of the high impedance exhibited by that winding, until the magnetic material of the core becomes saturated, at which instant the inductive impedance of the main winding drops to a relatively negligible level, and power is then transferrable to the output during the remainder of the pulse duration. Magnetic biasing of the core material, by the control winding effectively shifts its hysteresis-loop and saturation characteristic, such that controllably longer or shorter times are required for applied power pulses of uniform amplitude to bring the core to saturation, thereby achieving desired regulation of the channel's power output.

摘要： A trapezoidal current-versus-time waveform output stage of simple construction for a switched-mode power supply avoids unwanted heat generation encountered while dropping the voltage of the D.C. supply to drive the base of the output transistor (10) by deriving the energy for output- transistor (10) base drive from a bias winding (20) on the output transformer (14), storing that energy in the form of a current flowing through an inductor (26), and steering that current by means of a shunt transistor 32 selectably either into the base-emitter junction of the power transistor (10) or so as to reverse bias the base emitter junction of the power transistor (10) to ensure that rapid removal therefrom of its stored charge.

摘要： A switching power supply that comprises a base drive transformer, a switch device connected to one end of the transformer's primary winding, and a transistor having its base connected to one end of the secondary winding and its emitter connected to the other end of the secondary winding, also comprises a current-dependent voltage clamp connected across one winding of the transformer. The clamp circuit prevents the voltage across the primary winding from exceeding a predetermined value so long as the magnetizing current that flows in the primary winding when the switch device is opened does not exceed a predetermined value.

摘要： A single-ended, zero-current switching, forward converter circuit converts power from a current source to a voltage load in a succession of energy transfer cycles using a transformer constructed to have an effective leakage inductance L le , a capacitor (C) in series with the primary winding of the transformer, a switching device also in series with the primary winding, a unidirectional conducting device connected in series with the secondary winding in an orientation to conduct when the switching device is conducting, and a controller that selectively closes and opens the switching device to transfer energy from the capacitor via the effective primary leakage inductance to the load during an energy transfer cycle having a characteristic time scale determined by L le and C.
