Generate Positive and Negative Voltage by Combining Two DC Sources (.PDF Download)

    Feb. 16, 2017

    In 2012, I wrote two articles in Electronic Design that discussed several methods for generating a power signal that could go positive and negative in voltage using polarity reversal relays (“Turn Positive Voltages Negative with Relays”) and  using bipolar power supplies (“Bipolar Power Supplies Run the Gamut”). In this article, I present a third method for generating a power signal that could go positive and negative in voltage using two dc sources...
