Component open circuitAfter the capacitor is open circuit, it has no function as a capacitor. After capacitors in different circuits have open-circuit faults, the specific fault phenomena of the circuits are different. For example, hum sound occurs after the filter capacitor is opened, and there is

Filter capacitor:It is connected in parallel between the positive and negative poles of the circuit to remove the useless ac current in the circuit. Generally, large-capacity electrolytic capacitors are used, and other fixed capacitors are also used.Decoupling capacitor:Connected in parallel between

Capacitors are not ordinary daily necessities. We have checked them after getting the capacitors. If there is no problem, they can be installed and used. Otherwise, it will be very troublesome if something goes wrong. Therefore, we should check the metallized film capacitors after we get them. Befor

Calculated according to the capacitance formula, the size of the capacitance is not only related to the specifications of the capacitor, but also related to the thermal conductivity (Permittivity) of the dielectric. The performance of the dielectric affects the performance of the capacitor, and diff

Thin film capacitors have unique application advantages in many power electronics fields. Film capacitors have the characteristics of high voltage, high capacitance, and long service life, and the structural design of the film ensures that the capacitor has good self-healing properties. In the D

In power electronics, rectification is a form of electrical energy conversion that converts alternating current (AC) into direct current (DC).After the ac signal enters the rectifier circuit composed of power diodes, the resulting original rectified waveform emits a series of half-sine waves with si

The photovoltaic inverter is one of the core components of the photovoltaic system in the solar generator set. It needs to meet different functional requirements. It not only needs to ensure DC/AC conversion, but also needs to ensure the quality of the output power.As end customers and designers inc

CBB61 is a kind of CBB capacitor. CBB means polypropylene capacitor. 61 is its model. It is a starting and running capacitor commonly used for single-phase motors powered by ac mains power. We call it starting capacitor (Sometimes called capacitance).It is also used in electric water pumps, various

Capacitors are closely related to our lives, such as televisions, LED lights, switching power supplies, etc.The air conditioner is started by the capacitor of the outdoor unit. Do you all know that? If the capacitor is broken, the entire air conditioner will not cool, which is also a common fault th

As we all know, a single-phase ac motor is not like a three-phase motor. It can rotate when it is powered. It requires a starting torque to rotate, and the clockwise or counterclockwise direction of this torque determines the direction of the motor. There are many ways to start. Among them, capacito
