Varistor | Working Principle | Types | Metal Oxide Varistor …
Silicon carbide varistor For this we take MOV metal-oxide varistor which is the most common type of varistor. This type contains a ceramic mass of zinc oxide grains, in a matrix of other metal oxides (such as small amounts of bismuth, cobalt, manganese) sandwiched between two metal plates (the electrodes).

Efficiency and Innovation | 2020-06-03 | Industrial Heating
Silicon carbide is also being employed for radiant tubes because it has the capability of higher heat fluxes. This, in turn, means that more heat can be transferred to the load in less time, which reduces cycle time and, in effect, increases a given facility’s capacity.
Bus duct are the hollow conductors used to transfer …
Answer Posted / ashish malik Bus duct are the hollow conductors used to transfer electrical power and used for high current .These are hollow because flow of the high current exhibits small amount of current passing through the middle of conductor due to skin effect .

Replace your aging optocoupler gate driver - Power …
Silicon carbide (SiC) field-effect transistors (FETs) are increasingly popular in such appliions because they can switch faster than IGBTs. Regardless of whether you use IGBTs or SiC FETs as the power FET, switching faster means higher transient voltages (dv/dt) and larger common-mode transients, which can couple back to the gate driver inputs, corrupting the power FET’s gate-drive signals.
