ABSTRACT:
An AC-to-DC power converter controller reconstructs the output voltage of the power converter without a sample-and-hold circuit or an opto-coupler. The controller includes an accumulation module for accumulating a difference value obtained by subtracting a first representation of an output voltage of the power converter corresponding to a first sampling timing from the output voltage value sampled at a second sampling timing subsequent to the first sampling timing to obtain a second representation of the output voltage of the power converter corresponding to the second sampling timing. The accumulation module may set the second representation of the output voltage to a predetermined maximum value if the output voltage value sampled at the second sampling timing exceeds the predetermined maximum value, or to a predetermined minimum value if the output voltage value sampled at the second sampling timing is less than the predetermined minimum value.
