Calculation method of film capacitor series

Now talking about new energy, we believe that everyone will think of film capacitors. With the rapid advancement of electronic technology, the development of film capacitors in the future can be expected. So as a technician, do you know the calculation method for the series connection of film capacitors? What is the characteristic of the film capacitor?

The characteristics of the film capacitor are as follows:

1. Film capacitors can store charge and have the function of blocking DC

2. AC power can "pass" film capacitors

3. Capacitive reactance of film capacitor

Thin film capacitor series calculation method: The equivalent capacitance formula is similar to the resistance parallel: C=(C1*C2)/(C1+C2). For example, after two 100 microfarad capacitors are connected in series, it becomes a 50 microfarad capacitor. The two-capacitor series withstand voltage is the sum of the two, and the capacity is the reciprocal and the fraction of the two. The two-capacitor parallel withstand voltage is the value with low withstand voltage in both, and the capacity is the sum of the two. Simply put, the series withstand voltage rises and the capacity decreases. The parallel withstand voltage is constant and the capacity is increased.
