Disclosed is a pulse elimination circuit, a voltage detection circuit and a detection method, referring to a field of electronic circuit technology. The pulse elimination circuit comprises: a clock generation circuit configured to receive a logic signal and a first input signal and generate a clock signal according to the logic signal and the first input signal; a counter coupled with the clock generation circuit and configured to receive the clock signal and count a number of cycles of the clock signal to generate a second input signal; a signal output circuit coupled to the counter and configured to supply a first input signal to the clock generation circuit and generate a pulse elimination signal based on the second input signal. Therefore, in a process of voltage detection, this circuit can eliminate a false trigger caused by short pulse and improve voltage detection accuracy.
