Electronics Principles and Devices Rectifier with Filter

A half-wave rectifier with a capacitor-input filter is shown in Figure 2. The filter is simply a capacitor connected from the rectifier output to ground. RL represents the equivalent resistance of a load. We will use the half-wave rectifier to illustrate the basic principle and then expand the concept to full-wave rectification.

Understanding Capacitors

In a parallel combination of three capacitors, one plate of each capacitor is connected to one terminal of the source, while the other plate of each capacitor is connected to the other terminal of the source. As the capacitors are connected in parallel, they all have the same voltage V across their plates but they may store a different charge.

6 FAQs about [Is the capacitor connected to the input or output]

How is a capacitor selected?

In essence, the input capacitor is selected on the basis of these parameters, but in trial manufacture and evaluation, checks must be performed to ensure that the input voltage with ripples added do not exceed the withstand voltage, and that heat generation caused by the ripple current can be tolerated.

How to select input capacitors?

The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Ceramic capacitors placed right at the input of the regulator reduce ripple voltage amplitude.

What does a capacitor do in a power supply?

The first place you might expect to see capacitors are in power supplies of all sorts as filters and for decoupling. They act as charge reservoirs – providing quick current when the load needs it. Here are two oscilloscope shots that show the effect of not having and having a capacitor across the leads of a power supply.

What is capacitance of a capacitor?

Capacitance is the electrical property of a capacitor. The amount of energy that can be stored in a capacitor depends on its capacitance, which is measured in farads. The capacitance of a capacitor depends on several factors, including the surface area of the plates, the distance between the plates, and the type of dielectric material used.

How to choose a capacitor?

Based on the input voltage, the input current RMS current, and the input voltage peak-to-peak ripple you can choose the capacitor looking at the capacitor datasheets. It is recommended to use a combination of Aluminum Electrolytic (AlEl) and ceramic capacitors.

How do bulk capacitors work?

Bulk capacitors control the voltage deviation at the input when the converter is responding to an output load transient. The higher the capacitance, the lower the deviation. Therefore, the size of the input bulk capacitor is determined by the size of the output current transient and the allowable input voltage deviation.
