A system for regulating an output voltage to a particular value includes a control transistor which produces an output voltage when energized by an energizing voltage. A voltage divider formed as by a pair of transistors with a particular ratio of transconductances divides the magnitude of this output voltage by a ratio related to the ratio of the transconductances. The transistors in the voltage divider may be respectively CMOS n- and p- transistors. The divided output voltage is introduced to ...

A differential ECL signal is converted to a first current and a second current that are proportional to the ECL signal. An upper output transistor (16) and a lower output transistor (57) are selectively enabled and disabled by the first current. The second current is used to enable discharging of a storage capacitance of the lower output transistor (57) thereby substantially disabling the lower output transistor (57) before the upper output transistor (16) is enabled. In addition, a capacitor is...

A voltage regulator circuit is provided for a sensor that is connected in a two-wire scheme to a circuit comprising a power supply and a load. The circuit regulates the current flowing through the load when the sensor output is inactive and provides power to the sensor during periods of time when the input power of the regulator circuit is insufficient to do so. A current monitor and a voltage monitor are provided which utilize common circuit elements to control the current flowing through the c...

Voltage converter primarily for travelers to transform 220/240 volts A.C. to 110/120 volts A.C. The device is constructed of all solid state electrical components. It is designed so that the mounting bracket for the components also acts as a heat sink. The device includes a resistance across the output terminals to allow its use with a wide variety of appliances.

Voltage increasing converter having a very small volume, supplying a continuous voltage in the order of about 10 volts regulated accurately from a continuous voltage supply which can be less than one volt, the regulation being ensured by a negative-reaction circuit having a variable resistor, which consists of the drain-source path of a field-effect transistor.

Voltage control circuit having a DC motor, and including other instrumentalities, such as a rectifier, subject to damage by excessive emf as in braking, and means controlled by the counter emf for actuating relays which control resistances and correspondingly control a valve (tube) for opening circuit to the rectifier and thereby cutting it out of the circuit from the counter emf.

A voltage transformer comprising a hollow support insulator within which is arranged a main insulator and associated with this, a magnetic circuit, at least one primary winding and at least one secondary winding, together with necessary conductors. The main insulator is of tubular form and made up of a number of metal foil tube elements located inside each other in such a manner as to overlap each other partially but not completely, with insulator elements of tubular form arranged between them. ...

AC and DC voltage regulators are disclosed in which in each, the output voltage V.sub.out is related to V.sub.in x T.sub.s /T.sub.p, wherein V.sub.in is the unregulated input voltage and T.sub.s and T.sub.p are the number of turns of windings of an isolation transformer or the number of turns of different portions of the winding of an autotransformer. Either T.sub.s or T.sub.p is varied in discrete steps in order to control the product of V.sub.in and T.sub.s /T.sub.p to be within a preselected ...

The magnitude of a monitored voltage is detected with respect to a lower level and an upper level. The lower level is primarily defined by the breakdown potential of a Zener diode. The upper level is primarily defined by a predetermined potential difference between two signal voltages defined in different proportions to the monitored voltage by two different voltage divider networks connected to the Zener diode.

A voltage divider which can be manipulated so as to vary the output voltage thereof, prevents mechanical wear of the voltage divider element, provides continuous contact, and can be sealed so as to prevent interaction with the ambient atmosphere including first and second non-conductive substrates with a predetermined spaced portion therebetween. A first conductive strip on the second substrate is depressed across the spaced portion so as to contact at least one of a plurality of conductive taps...
