A half-wave controlled rectifier with a purely resistive load has a delay in its output waveform due to the nature of its operation.

In a half-wave controlled rectifier, only half of the input AC signal is allowed to pass through, while the other half is blocked. This is achieved by using a diode as a rectifying element.

When the input AC signal is positive, the diode is forward biased and allows the current to flow through the load in the desired direction. However, when the input AC signal is negative, the diode becomes reverse biased and blocks the current flow.

This switching action of the diode causes a delay in the output waveform. When the input AC signal changes polarity from positive to negative, there is a brief period where the diode needs to switch from its conducting state to its non-conducting state. This switching delay results in a small gap or dead time in the output waveform.

The delay in the output waveform can be minimized by using fast-switching diodes and optimizing the control circuitry. However, there will always be some inherent delay due to the nature of the rectification process in a half-wave controlled rectifier.
