“…This idea is originated from one of the earliest papers on SM controlled power converters [2], which suggests that under SM control operation, the control signal of equivalent control approach u eq in SM control is equivalent to the duty cycle control signal d of a PWM controller. The proof was later provided in the papers [12], [13]. It has been shown that at a high switching frequency, the control action of a sliding mode controller is equivalent to the duty cycle control action of a PWM controller.…”

Abstract-This paper addresses the issues concerning the implementation of a pulse-width-modulation based sliding mode controller for boost converters. The methods of modelling the system and translation of the SM control equations for the PWM implementation are illustrated. It is shown that the control technique is easily realized with simple analog circuitries. The proposed system is verified by experimental measurements.

“…Different works present synthesis of LFR operating at a constant switching frequency, sometimes with the aim to shorten the distance between both operation modes. In that sense, in [4] a correspondence between the equivalent control in sliding mode and the zero dynamics nonlinear pulse width modulation control [5] is presented in order to design a LFR based on a boost converter. However, its main drawback is the need to use an analog divisor.…”

The synthesis of a Digital Loss-Free Resistor (DLFR) based on a boost converter in Pulse-Width-Modulation (PWM) operation is presented. The proposed control law is obtained by applying discrete-time sliding mode control theory on the discrete-time model of the boost converter to control the input current. The control law calculates the duration of the switch on-time at the beginning of each switching period in order to reach the proposed discrete-time sliding surface. The resulting digital Loss-Free Resistor (DLFR) can be used as a preregulator for power factor correction in one-phase circuits. Simulations are in good agreement with theoretical predictions.

“…The direct search of PWM control strategy that guarantees a desired steady-state behavior is not a simple task. However, it was demonstrated in [6] that the non-linear PWM control that imposes S(x)=0 in steady-state in a switching converter was the equivalent control u eq (x) found in the analysis of the converter in sliding-mode operation. In the case of the PWM control, there is an additional term which describes the converter start-up from initial conditions until steady-state where the ideal sliding dynamics around the switching surface is observed.…”
