6 FAQs about [What is the principle of capacitor current reversal]
What is current reversal?
Current reversal is defined as the changing of the direction of current flow through the capacitor. In an underdamped RLC circuit, the energy in the circuit oscillates back and forth between the capacitance and the inductance. In this case, both the capacitor voltage and current oscillate with the same percentage of reversal.
How does reversal affect a capacitor?
The effect of reversal on a particular capacitor varies with the design of the capacitor, the voltage at which it is being operated, the temperature, the pulse repetition rate, and other factors.
How does a transient voltage reversal affect a capacitor?
The damage inflicted on a capacitor by a transient voltage reversal is a nonlinear function of the degree of reversal. As shown in Figure 2, the change in life between 80 and 85 % reversal is much greater than the change between 20 and 30 % reversal.
What is voltage reversal?
I. WHAT IS REVERSAL? Voltage reversal is defined as the changing of the relative polarity of the capacitor terminals, such as may be experienced during a ringing or oscillating pulse discharge, during AC operation, or as the result of DC charging the capacitor in the opposite polarity from which it had been previously DC charged.
Why do DC capacitors need a high reversal rating?
DC capacitors must be designed for the highest level of voltage reversal (normal or fault) that may be experienced in service. High reversal ratings result in significant reductions in energy density and increases in size and cost.
How does a capacitor work in a DC Circuit?
