Detection method: 

the single-phase bridge rectifier stack is a rectifier assembly packaged together by 4 rectifier diodes in a full-wave rectifier circuit connection mode;

the way to judge the bridge stack is to measure the forward and reverse resistance of 4 diodes with a multimeter;

If the measured forward resistance of the diode is infinite, it means that the internal circuit of the diode is open;

If the measured reverse resistance of the diode is close to zero, it indicates that the diode has broken down;

Output voltage theory: 

1. in the single-phase bridge rectifier circuit, if a filter capacitor is connected, when the load is open, the output voltage (that is, the voltage across the capacitor) is the peak value of the AC input voltage, that is: U output=1.414*U Input, that is, root 2 times the input voltage.

this conclusion is applicable to bridge, full-wave, and half-wave rectifier circuits.

but under load, it is generally designed to be 1.2 times U input. the larger the filter capacitor, the higher the output voltage, and vice versa.

2. in the single-phase bridge rectifier circuit, if there is no filter capacitor, when the load is open, the output voltage is 0.9 times the AC input voltage, that is: U output = 0.9 * U input.

When loaded, the formula remains the same, still: U output = 0.9 * U input. this bridge stack is suitable for circuits within 700V. 5V, 12V, 24V, 36V, 48V, 72V-220V, 380V, are all available!
