Abstract
A switching rectifier circuit includes a pulse width modulation controller, a voltage switching circuit, a pulse width modulation comparator, an error amplifier, a voltage reference, a high threshold voltage comparator and a low threshold voltage comparator. A varying output voltage of the voltage regulator is sampled and compared to a high threshold voltage reference and a low threshold voltage reference. When the sampled output voltage is equal to or greater than the high threshold voltage reference the output voltage is decreased. When the sampled output voltage is equal to or less than the low threshold voltage reference the output voltage is increased.
