Was wondering what would happen to the output voltage when the input voltage exceeds the PIV/PRV.

A half wave rectifier is an electronic circuit that converts an alternating current (AC) input signal to a direct current (DC) output signal by allowing only half of the input signal to pass through.
"Vi > PIV" means that the peak input voltage (Vi) is greater than the peak inverse voltage (PIV) of the rectifier. This is an important consideration in designing and selecting a half wave rectifier to ensure it can handle the input voltage without damaging the components.
A half wave rectifier works by using a diode to block the negative portion of the AC input signal, resulting in a pulsating DC output signal. The output voltage is equal to the peak value of the input voltage.
The main difference between a half wave rectifier and a full wave rectifier is that a half wave rectifier only allows one half of the input signal to pass through, while a full wave rectifier allows both halves of the input signal to be converted to DC.
The advantages of a half wave rectifier include its simplicity and low cost, as it only requires a single diode. However, it has a lower efficiency compared to a full wave rectifier and produces a pulsating DC output which may require additional filtering for certain applications.
