11Alternating current — (green curve). The horizontal axis measures time; the vertical, current or voltage. In alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge …
12Rectifier — A rectifier is an electrical device that converts alternating current (AC) to direct current (DC), a process known as rectification. Rectifiers have many uses including as components of power supplies and as detectors of radio signals. Rectifiers …
13Pylon transformer — Because of weight restrictions transformers for pylon transformers are only built for voltages under 30kV.Pylon transformers are often used for the power supply of facilities outside settlements, such as farmyards or pumping stations at voltages… …
14Common-mode interference — In telecommunication, the term common mode interference has the following meanings: Interference that appears on both signal leads (signal and circuit return), or the terminals of a measuring circuit, and ground. A form of coherent interference… …
15Voltage multiplier — Villard cascade voltage multiplier. A voltage multiplier is an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage, typically by means of a network of capacitors and diodes. Voltage multipliers can be… …
16Push–pull converter — A push–pull converter is a type of DC to DC converter that uses a transformer to change the voltage of a DC power supply. The transformer s ratio is arbitrary but fixed; however, in many circuit implementations the duty cycle of the switching… …
17High leg delta — A high leg delta (also known as wild leg or red leg delta) is a type of electrical service connection sometimes found in older three phase electric power installations. This type of service is supplied by a transformer having four wires coming… …
