N2 - In this paper, we propose a methodology to derive a pulse-width modulation (PWM) control for the inner current loop of the boost power factor correction (PFC) converter. The methodology is based on the general sliding mode control theory. It leads to a robust current control that achieves accurate input current tracking under all practical conditions. The design of the control parameters is also presented, which is based on the existence condition and the frequency response analysis. The derived control can be implemented in analog circuitries as an application-specific controller or as an add-on feedforward control embedded in standard PFC controller circuits.
