Abstract :
A power converter control method called charge control is studied. A complete small-signal analysis is performed for the control scheme. Subharmonic oscillation similar to that of current-injection control is found, and the relationship between the subharmonic oscillation and line/load condition of charge control is defined. Design guidelines which guarantee the stability of the control system under given line and load ranges are proposed. The small-signal model was confirmed experimentally
