    In inverter operation, the situation that a valve arm continues conduction at the end of the normal conduction interval or at the end of the hold-off interval. (electronic) (power) conversion Change of one or more of the characteristics of an electric power system essentially without appreciable loss of power by means of electronic valve devices .

    The phenomenon can be avoided by connecting a minimal resistive load on the transformer secondaries or by interrupting the applied voltage by a 3-phase interrupting device such as a ganged (3-pole) circuit breaker. [8] In many cases, it also suffices to unground the transformer in a Δ configuration, which increases the line shunt impedance.

    Linear voltage-regulating circuit and usually noise-filtering capacitors; usually a simpler circuit (and simpler feedback loop stability criteria) than switched-mode circuits. Consists of a controller IC, one or several power transistors and diodes as well as a power transformer, inductors, and filter capacitors. Some design complexities ...

  9. Motor–generator - Wikipedia

    en.wikipedia.org/wiki/Motor–generator

    The motor–generator set may contain a large flywheel to improve its ride-through; however, consideration must be taken in this application as the motor–generator will lose speed and may draw a large current when power returns or the circuit-breaker is re-closed. If the speed loss is excessive (the power outage is too long), the re-closure ...
