Abstract
A voltage measurement system and method is provided. Aspects include a comparator having a positive and a negative input terminal, a processor configured to supply a reference voltage signal to the negative input terminal, wherein the positive input terminal receives an input voltage, setting the reference voltage signal to a zero voltage signal, determine a line frequency of the input voltage based on a timing signal from the comparator and determining a first pulse width of the input signal based on the timing signal, set the reference voltage to a PWM signal with a fixed duty cycle, receive the timing signal from the output of the comparator, determine a rising edge and a falling edge associated with the input voltage based on the timing signal, and determine a peak value of the input voltage based on a second pulse width between the rising and falling edge.
