The negative swing of the output will not dip below about −0.6 V, assuming a silicon PN diode. [1] A clamper (or clamping circuit or clamp) is an electronic circuit that fixes either the positive or the negative peak excursions of a signal to a defined voltage by adding a variable positive or negative DC voltage to it. [2]
In electrical engineering specifically, the transient response is the circuit’s temporary response that will die out with time. [1] It is followed by the steady state response, which is the behavior of the circuit a long time after an external excitation is applied.
A terminal fault is a fault that occurs at the circuit breaker terminals. The circuit breaker interrupts a short-circuit at current zero, at this instant the supply voltage is maximum and the recovery voltage tends to reach the supply voltage with a high frequency transient. The normalized value of the overshoot or amplitude factor is 1.4.
Baker clamp is a generic name for a class of electronic circuits that reduce the storage time of a switching bipolar junction transistor (BJT) by applying a nonlinear negative feedback through various kinds of diodes. The reason for slow turn-off times of saturated BJTs is the stored charge in the base.
There is also a recovery concern: a diode's current will not decrease immediately when switching from forward-biased to reverse-biased, because discharging its stored charge takes a finite amount of time (t rr or reverse recovery time). [1] In a diode OR gate, if two or more of the inputs are high and one switches to low, recovery issues will ...
Turning off the switch causes the voltage across the inductor to reverse and the current to flow through the freewheeling diodes Da+ and Da-, decreasing linearly. By controlling the switch on-time, the topology is able to control the current in phase with the mains voltage, presenting a resistive load behavior ( Power-factor correction capability).
The diode must immediately enter into forward conduction mode as the driving current is interrupted. Most ordinary diodes, even "slow" power silicon diodes, are able to turn on very quickly, [3] in contrast to their slow reverse recovery time. These are sufficient for snubbing electromechanical devices such as relays and motors.
