Let us consider an inductive load taking a lagging current I at a power factor cosΦ1. For us to improve…
Solid-state soft starting is the most commonly used technique for starting induction motors. It provides a smooth build-up of current…
The Impact Avalanche Transit Time (IMPATT) diode is a high power radio frequency (RF) generator that operates from 3 to…
Servo motors are typically employed in closed-loop position control; for example let us consider the following application, where the angular…
The Shockey diode is a four layer sandwich of PNPN semiconductor material very similar to the SCR but without a…
A 3-phase autotransformer is typically employed where star or delta starting provides insufficient starting torque. Each phase of an autotransformer…
The function of the manipulating device is to influence the process variable. Its main purpose is to regulate a mass…
Features of a Diac The diac is a two-terminal, semiconductor, bi-directional switching device. It can conduct in both directions. The…
ZigBee is an open wireless standard for low-rate networks. It is an IEEE standard 802.15.4 protocol. The physical layer radio…
The unijunction transistor (UJT) is a three terminal, single-junction device which exhibits negative resistance and switching characteristics totally unlike those…
