Abstract
A power converter circuit senses the output voltage (Vo) and controls the converter's duty cycle (d) to provide a steady output current (Io) or input power (Pin) in each switching cycle (T). During an initial period (Tramp), the controller provides a possibly smaller target current (Iramp) to reduce the system stress while the output voltage rises to a suitable value (InitVtar).
