VARIABLE condensers are now so commonly employed in radio receivers to tune circuits including a ... Permeability Tuning in Radio-Frequency Circuits. Nature 133, 956 (1934). https ...

In a sinking circuit, current flows from the voltage supply, through the load, to the switch, and then to ground. NPN transistors are usually associated with sinking circuits. In a sourcing ...

This is particularly true with the introduction of variable frequency drives (VFDs). Historically, you were stuck with a fixed speed on a prime mover or limited to using non-efficient, cost ...

Variable-frequency types. There are three common types of VFDs. Current source inversion (CSI) has been successfully used in signal processing and industrial power applications. CSI VFDs are the only ...

Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a couple of typical scenarios commonly encountered ...
