The input signal from the alternating current source E1 is supplied to the input of the alternating current comparator through a separation transformer Tr1, diodes D1, D2 and a bridge resistive ...

Using a conventional comparator, you would need to place an additional high-voltage switch in series with the comparator input in order to protect it. (Part 2 of this article looks at the PWM ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that ...
