In a preferred embodiment, a voltage converter comprises a voltage converter circuit, an output adjuster and a controller. The controller provides a control signal at a duty ratio determined dynamically by a set of input signals. The dynamic output adjuster determines the set of input signals by adjusting the ac component of an output voltage based on a gain Q. The dynamic output adjuster alleviates dependence on the value of Rc under leading edge modulation in either analog or digital converter systems. In addition to delivering the desired left half plane zero effects, dynamic output adjustment reduces the value of the output ripple. As a result, modern control methods such as input-output linearization can be used to design both boost and buck-boost PWM converters if only left half plane zero effects are present.
