actually a diode is forward biased by at least 0,7 volts.so what it means is that when it is removed that 0,7 voltage drop on the diode is eliminated thus increasing ripple voltage
To measure the ripple frequency in a bridge rectifier circuit, use an oscilloscope to observe the output voltage waveform. The ripple frequency is typically twice the input AC frequency if the diodes are functioning properly since the rectifier conducts during both halves of the AC cycle. If the ripple frequency is lower than expected, it may indicate that one or more diodes are open, preventing proper rectification. Comparing the measured frequency to the expected value helps diagnose the condition of the diodes.
you can't have half wave rectified polyphase AC power, unless you are using only one of the phases. however with only one diode from each phase of three 50 Hz phases the ripple frequency is 150 Hz, with two making a full three phase bridge the ripple frequency is 300 Hz. perhaps that was what you meant.
How often the ripple occurs i.e. times the ripple occurs per second. The ripple should be a repeating pattern. Figure out where the ripple repeats and measure how long each repetition takes. Measure this in seconds. The frequency is 1/Time where time is the time measured previously.
twice the frequency that is rectified.
It's double the frequency of the power source.
The three phase bridge rectifier has the highest ripple frequency. In a 60 Hz system, the ripple frequency would be 360 Hz. If it were a one phase bridge rectifier, the ripple frequency would be 120 Hz.
Measuring ripple frequency would determine if a diode were open in a bridge rectifier circuit because the ripple frequency is normally twice the input frequency in a functioning full wave bridge rectifier. If one diode were open, the ripple frequency would only be the input frequency. Note: This is true for single phase or bi-phase operation. Three phase operation is more complex, but still doable - You would expect three times input frequency in normal state, and two times (asymmetric) with one open diode.

The ripple frequency of a half-wave rectifier is the same as the input frequency.

If the rectifier is wye connected, ripple will increase. If it is delta connected, ripple will substantially increase. Whether or not the rest of the rectifier, filter, and regulator are damaged will depend on how much current is being pulled by whats left, and by how deep the ripple actually becomes.
The minimum frequency of ripple in the output typically depends on the specific application and the design of the circuit involved. In power supplies, for example, ripple frequency is often determined by the rectification method used; for full-wave rectifiers, it is double the input frequency, while for half-wave rectifiers, it matches the input frequency. To provide a precise answer, additional context regarding the circuit type or application is necessary.
