A shunt is a device that is designed to provide a low-resistance path for an electrical current in a circuit. ... All semiconductor diodes have a threshold voltage ...
A capacitive fixed-fixed beam RF MEMS switch, as shown in Fig. 1(a), is in essence a micro-machined capacitor with a moving top electrode, which is the beam. It is generally connected in shunt with the transmission line and used in X- to W-band (77 GHz and 94 GHz) RF MEMS components. An ohmic cantilever RF MEMS switch, as shown in Fig. 1(b), is ...
TVS diode as array. A transient-voltage-suppression diode may be either unidirectional or bidirectional. A unidirectional device operates as a rectifier in the forward direction like any other avalanche diode, but is made and tested to handle very large peak currents.
In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits. Failures most commonly occur near the beginning and near the ending of the lifetime of the parts, resulting in the bathtub curve graph of failure rates.
Ohmic metal-semiconductor contacts are made to both the n-type and p-type sides of the solar cell, and the electrodes connected to an external load. Electrons that are created on the n-type side, or created on the p-type side, "collected" by the junction and swept onto the n-type side, may travel through the wire, power the load, and continue ...
The goal shunt compensation is to connect a device in parallel with the system that will improve voltage and enable larger power flow. This is traditionally done using shunt capacitors and inductors (reactors), [13] much like Power Factor Correction. The most common shunt compensation device is the Static VAR Compensator (SVC). [14]
A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state ... controlled rectifiers, speed control of DC shunt motors, SCR ...
Typical use of TL431 in SMPS. Shunt resistor R3 maintains minimum TL431 current, series resistor R4 is part of frequency compensation network (C1R4) [31] [32] In the 21st century, the TL431, loaded with an optocoupler's light-emitting diode (LED), is the de facto industry standard solution for regulated switched-mode power supplies (SMPS).
