What are the considerations for designing bridge rectifier circuits?

When using a bridge rectifier circuit to provide DC output from AC input, the following points need to be considered:
Voltage drop: Never forget that the current flowing through the bridge rectifier circuit will pass through two diodes. As a result, the output voltage will decrease by this amount. Due to the use of silicon diodes in most bridge rectifier circuits, the voltage drop is at least 1.2 volts and increases with the increase of current. Therefore, the maximum achievable voltage output is at least 1.2 volts lower than the peak voltage of the AC input.
Calculate the heat dissipated in the rectifier: The diode will cause the voltage to drop by at least 1.2 volts (assuming a standard silicon diode), and as the current increases, the voltage will rise. It is caused by the standard voltage drop across the diode and the resistance inside the diode. Note that the current passes through the two diodes in the bridge during any half cycle. Firstly, there is a set of two diodes, followed by another one. It is necessary to refer to the datasheet of the diodes or electronic components of the entire bridge rectifier circuit to view the voltage drop at the assumed current level. Voltage drop and current passing through the rectifier circuit generate heat, which needs to be dissipated. In some cases, this can be easily dissipated through air cooling, but in other cases, the bridge rectifier circuit may need to be bolted to the radiator. For this reason, many bridge rectifier circuits are constructed to be fixed to the radiator with bolts.
Peak reverse voltage: It is very important to ensure that the peak reverse voltage of the bridge rectifier circuit or a single diode is not exceeded, otherwise the diode may break down. The PIV rating of the diodes in the bridge rectifier circuit is lower than the rating required for two diode configurations used with a center tap transformer. If the diode voltage drop is ignored, for the same output voltage, the diode PIV rating required for a bridge rectifier circuit is half that of a center tap rectifier circuit. This may be another advantage of using this configuration. The peak reverse voltage across the diode is equal to the peak secondary voltage Vsec, because during half a cycle, diodes D1 and D4 conduct, while diodes D2 and D3 are reverse biased. The full wave bridge rectifier circuit displays peak reverse voltage assuming there is no voltage drop across a perfect diode. Using this, it can be seen that points A and B will have the same potential, and points C and D will also have the same potential. This means that the peak voltage from the transformer will appear on the load. The same voltage also appears on each non-conductive diode.
But in a bridge rectifier circuit, two diodes connected in series conduct during each half cycle. Therefore, the voltage drop occurs due to two diodes equal to 1.4 volts (0.7+0.7=1.4 volts). However, the power loss caused by this voltage drop is very small.
