Abstract
A voltage regulator for providing a predetermined output voltage from an unregulated voltage input is described where the output voltage is compared with a reference voltage to generate one or more control signals which in turn activate boost regulators which inject voltage onto the output. Each boost regulator utilizes a transformer for injecting the voltage onto the output and a bypass diode across the transformer to permit the input voltage less the diode voltage drop to appear at the output when the boost regulator is not activated.
