The reaction of the capacitor when the inductor leads the voltageWhen the rate of voltage change on the inductor is higher than the rate of current change, the inductor is inductive, and the voltage is ahead of the current. Under such conditions, we discuss the reaction of the capacitor.The phase relationship between voltage and currentIn circuitry, the phase relationship between voltage and current refers to the time difference and Angle difference between them. In an AC circuit, the phase rela

Power supply regulator (50Hz or 60Hz)Working principle and structural characteristicsThe power frequency power regulator is mainly for AC mains with a frequency of 50Hz (the mains frequency of most countries such as China) or 60Hz (some countries such as the United States). This type of regulator is usually based on the principle of electromagnetic induction, and the common inductive regulators and autotransformer regulators. The induction regulator adjusts the output voltage by changing the tur

The situation where the primary winding of a booster transformer is connected in series with the main power supply and the secondary winding is connected in parallel with the main power supply is not common in practical applications, because this connection method usually does not bring the expected benefits and may introduce unnecessary complexity and potential risks. However, assuming that this configuration is for a specific function, we can explore its possible purpose and application scenar

Zener breakdown voltage and avalanche breakdown voltage are two different breakdown mechanisms in semiconductor devices, especially diodes. The breakdown voltage caused by these two mechanisms is different, mainly because of their different physical mechanisms and occurrence conditions.Zener breakdownZener breakdown occurs in a reverse-biased PN junction, and when the applied reverse voltage is high enough, the electric field strength in the PN junction is enough to make the electrons in the val

Ac circuit breaker and DC circuit breaker operation and switching differenceThere are some important differences between AC circuit breakers and DC circuit breakers in terms of operation and switching, and these differences mainly stem from the differences in the physical characteristics of AC and DC.Differences in operating principlesAc circuit breakers and DC circuit breakers have different operating principles. Ac circuit breakers use the periodic change of alternating current and rely on the

The most serious faults in a power system usually refer to those that pose the greatest threat to system stability, equipment safety, and power supply reliability. Here are some of the most common types of serious failures in power systems and their effects:Three-phase Short CircuitThree-phase short circuit is one of the most serious faults in the power system, it occurs between the three phases of the wire or between one or more phases and the ground short. This fault will lead to a large short
