41Charge pump — 2 stage charge pump with DC voltage supply and a pump control signal S0 A charge pump is a kind of DC to DC converter that uses capacitors as energy storage elements to create either a higher or lower voltage power source. Charge pump circuits… …
42Control of the National Grid — The National Grid is the high voltage electric power transmission network in Great Britain, connecting power stations and major substations, and has a synchronized organization such that electricity generated anywhere in Great Britain can be used …
43Northeast blackout of 2003 — States and provinces that experienced the blackout; not all areas within these political boundaries were affected. The Northeast blackout of 2003 was a widespread power outage that occurred throughout parts of the Northeastern and Midwestern… …
44Thyristor — The thyristor is a solid state semiconductor device with four layers of alternating N and P type material. They act as bistable switches, conducting when their gate receives a current pulse, and continue to conduct for as long as they are forward …
45Decoupling capacitor — A decoupling capacitor is a capacitor used to decouple one part of an electrical network (circuit) from another. Noise caused by other circuit elements is shunted through the capacitor, reducing the effect they have on the rest of the circuit.… …
46Vacuum tube — This article is about the electronic device. For experiments in an evacuated pipe, see free fall. For the transport system, see pneumatic tube. Modern vacuum tubes, mostly miniature style In electronics, a vacuum tube, electron tube (in North… …
47Motor controller — A motor controller is a device or group of devices that serves to govern in some predetermined manner the performance of an electric motor.[1] A motor controller might include a manual or automatic means for starting and stopping the motor,… …
48Voltage regulator — A popular three pin 12 V DC voltage regulator IC. A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level. A voltage regulator may be a simple feed forward design or may include negative feedback …
49Valve audio amplifier - technical — Circuitry and performance Characteristics of valves Valves are very high input impedance (near infinite in most circuits) and high output impedance devices. They are also high voltage / low current devices.While valves themselves are described… …
50Multivibrator — A multivibrator is an electronic circuit used to implement a variety of simple two state systems such as oscillators, timers and flip flops. It is characterized by two amplifying devices (transistors, electron tubes or other devices) cross… …
