How do I add a bridge rectifier circuit to Proteus?

Add a bridge rectifier circuit step.

1. Place the device window, and click P to display the pick devices window;

2. Select Diodes in category, and select Bridge Rectifiers in sub-category to add;

A "rectifying circuit" is a circuit that converts alternating current energy into direct current energy. Most rectifier circuits consist of transformers, rectifier main circuits, and filters, among others. It is widely used in the speed regulation of DC motors, the excitation adjustment of generators, electrolysis, electroplating and other fields.

A rectifier circuit usually consists of a main circuit, a filter, and a transformer. After the 70s of the 20th century, the main circuit was mostly composed of silicon rectifier diodes and thyristors. The filter is connected between the main circuit and the load and is used to filter out the AC component of the pulsating DC voltage.

The transformer is set up or not on a case-by-case basis. The function of the transformer is to achieve the matching between the AC input voltage and the DC output voltage and the galvanic isolation between the AC grid and the rectifier circuit.

Place the device window, click p, the pick devices window appears, select diodes in category, and select bridge rectifiers in sub-category, all of which are bridge stacks.

Mine is the English version of sp4, and I guess it's all about the same.

The brideg 1 rectifier bridge is a diode, while the brideg 2 rectifier bridge is a packaged rectifier bridge.

First click on the English word for bridge, and then enter this word in Proteus' library.

There is a picture, but does the oscilloscope show a RMS or a peak? You need to make sure.

According to your parameters, select the same or similar model in the library.

Because the ground terminal on the negative pole after rectification is not connected, the terminal can not be directly in contact with the wire, there must be a little distance, and then connect it with a section of wire, there must be a node, and yours does not have a node. See diagram below.

The efficiency of bridge rectification is that after 220V AC through bridge rectification, DC of about +300V can be obtained, so the first step is no problem.

The filter voltage has not changed, because the capacitor you choose is wrong, the main filter C1 of the power supply uses a polar electrolytic capacitor, and you use a non-polar capacitor, you can replace it with a polar electrolytic capacitor.

1. The bridge rectifier circuit has an average load current of 1 times the average current of each diode. (The average is the average current that passes through a cycle). Each diode works only in half a cycle.

2. If the output of the single-phase bridge rectifier circuit does not have electrolytic capacitor filtering, the output voltage is several times of the secondary voltage (RMS) of the transformer. The DC voltage output after the whole and quietly matching the skin flow has a poor degree of smoothness (the waveform is pulsating DC), and the stability is relatively poor.

3. If the output of the single-phase bridge rectifier circuit is filtered with electrolytic capacitors, the output voltage is times of the secondary voltage (RMS) of the transformer. The DC voltage output after rectification filtering has a good degree of smoothness (the waveform is close to a straight line), but its stability is still relatively poor.

4. If the output of the single-phase bridge rectifier circuit is equipped with an electrolytic capacitor filter with a voltage stabilization circuit, the output voltage is determined by the voltage stabilization circuit. After rectification, filtering, voltage stabilization (the voltage regulator tube plays a role in voltage stabilization in the circuit), the output DC voltage, the smoothness is good (the waveform is a straight line), and its stability is relatively good.
