Abstract
A pulse-width control method is used to regulate output voltage for a DC-DC converter powered by a constant-current source. In a constant-current input converter, the output voltage rises as the transistor switching duty ratio is decreased and falls when the duty ratio is increased. Regulation is achieved by increasing the duty ratio when the output current decreases and decreasing the duty ratio when output current increases. This is the reverse of the technique used with constant-voltage input.
