“Two halves make a whole” is a very old and often true maxim. For example, it’s almost always true when said about AC phase angle power control. You rarely want significant alternating half-cycle ...
Abstract: This paper studies the relation between the fundamental frequency equivalent impedance of the TCSC and the basic frequency reactance of the TCR, A new concept of equivalent capacitor C/sub T ...
Melbourne, Fla. – New surface-mount thyristor circuit protection devices from Littelfuse Inc. in the Surgector series are specifically designed to safeguard telecom equipment. Surgectors protect ...
Abstract: With the recent development of DC system, a circuit breaker capable of limiting or blocking fault current has become indispensable. Recently, HDCCB (Hybrid DC Circuit Breaker), which ...
A dc motor supplied with a fixed voltage will run at a fixed speed. Today, the most common way of controlling their speed is by the use of dc variable speed drives, as Rob Easthope explains The basic ...
Littelfuse says it can supply a silicon-controlled rectifier (SCR) thyristor circuit protection device with a junction temperature of 150°C in a surface-mount package. The SJ series thyristors have a ...
Littelfuse, Inc., has introduced an ultra-low capacitance protection thyristor. An ultra-low capacitance protection thyristor from Littelfuse, Inc., the SDP Series SIDACtor® Protection Thyristor, ...
A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...
RJCS Series Current Monitoring Solid State Relay is capable of switching 50-amp single phase AC loads at up to 660 VAC when controlled by a 4-32 VDC signal. Its internal current sensing circuitry ...
