This voltage controlled switch circuit operates when a voltage level which is previously adjusted is applied to the input. Circuit is designed for 24V supply but can be used in a range of 18V-36V.

In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

In early 2006, KCP&L executives looked for ways to reduce system peak demand. The distribution automation engineering group proposed a voltage reduction option called dynamic voltage control (DVC).

ABB has released the Switching Control Sentinel (SCS) device designed for high-voltage circuit breakers. Voltage and current transients generated during switching of high-voltage circuit breakers are ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!
