Starting capacitors principle

Starting capacitors refer to AC electrolytic capacitors or polypropylene and polyester capacitors used to start single-phase asynchronous motors. The single-phase current flowing through a single-phase motor cannot generate a rotating magnetic field, and a capacitor is needed to separate the phases. The purpose is to make the current in the two windings produce a phase difference [...]

The difference between high frequency and low frequency capacitors

The difference between high frequency and low frequency capacitors: 1. Low-frequency capacitor have large capacitance and are prone to leakage, while high-frequency electrolytic capacitor will not. 2. The internal resistance of low-frequency capacitor is larger than that of high-frequency electrolytic capacitor. 3. The capacity of high frequency capacitor is generally not as large as that of [...]

The role of decoupling capacitors

The decoupling capacitors is mainly to remove the interference of high frequency such as RF signal, and the way of interference is through electromagnetic radiation. In fact, the capacitor near the chip also has the function of storing energy, which is second. You can think of the total power source as the Miyun Reservoir. Every household [...]

Why do LED drive power supply need aluminum electrolytic capacitors?

An important reason for the low lifespan of the LED drive power supply is the insufficient lifespan of the aluminum electrolytic capacitors required for the drive power supply. When working for a long time, the ambient temperature inside the LED lamp is very high, which causes the electrolyte of the aluminum electrolytic capacitor to be quickly [...]
