The basic principle, advantages and disadvantages of resistive and capacitive depressurization

Views:2     Author:Site Editor     Publish Time: 2018-04-03      Origin:Site

The advantages of resistive and capacitive depressurization:

 

Small size; low cost.

 

The drawback of resistive and capacitive depressurization:

 

Non-isolated power supply, unsafe;

 

Can not be used for high-power load;

.

Not suitable for capacitive and perceptual load;

 

Not suitable for dynamic load.

 

Capacitor charging and discharging principle.

 

 

Capacitance is a passive device which stores energy in the form of electric field. The charge-discharge process of capacitors is essentially the process of obtaining and releasing electrons from two parallel conducting plates.

 

Capacitor charging:

 

When the electric field intensity E in the capacitor is less than the external power supply voltage U at the two ends of the capacitor, the capacitor begins to charge. At this point, the capacitor positive electrode loses electrons, the negative electrode gets electrons, and the internal electric field E increases until the voltage U is equal to the external voltage, and the charge ends.
