Abstract	In this paper, an adaptive droop resistance (ADR) technique can compensate for the adaptive voltage positioning (AVP) control in a boost dc-dc converter. A loop analysis is derived with the AVP technique to show the effects of the right-half-plane (RHP) zero. When the value of RHP zero is above the equivalent series resistance (ESR) zero, constant output impedance can be guaranteed by the proposed compensation method. Once the value of RHP zero is below five times of ESR zero, the proposed ADR technique can vary the droop resistance to track the variation of the load current to increase the system stability. In case of load current variation, the output impedance is proven constant due to the implementation of the AVP technique in the boost converter. The transient response time is 22 μS when a 200-mA load current step occurs, which is faster than that of a conventional boost converter. Even at heavy loads, the ADR technique can ensure a fast and stable transient response without being affected by the RHP zero. The experimental results demonstrate that the proposed method can increase system stability and guarantee a fast transient response in the design of a boost converter with the AVP technique.
