2. Braking chopper - Wikipedia

   en.wikipedia.org/wiki/Braking_chopper

   This arises, for example, when a magnetized motor is being rotated by an overhauling load and so functions as a generator feeding power to the DC voltage intermediate circuit. [ 1 ] [ 2 ] They are an application of the chopper principle , using the on-off control of a switching device.

3. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A small circuit breaker typically has a manual control lever to switch the circuit off or reset a tripped breaker, while a larger unit may use a solenoid to trip the mechanism, and an electric motor to restore energy to springs (which rapidly separate contacts when the breaker is tripped).

   The same way by equating the average inductor current during the turn-on and turn-off time, we can get the average voltage by [6] V a v e = α V s {\displaystyle V_{ave}=\alpha V_{s}} where V a v e {\displaystyle V_{ave}} is the average output voltage , α {\displaystyle \alpha } is the duty cycle and V s {\displaystyle V_{s}} is the source ...

6. Multiway switching - Wikipedia

   en.wikipedia.org/wiki/Multiway_switching

   In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.

7. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
