Abstract-In this paper a fixed-frequency quasi-sliding control algorithm based on switching surface zero averaged dynamics (ZAD) is reported. This algorithm is applied to the design of a Buck-based inverter, and implemented in a laboratory prototype by means of a field programmable gate array (FPGA), taking into account processing speed versus computational complexity trade-off. Three control laws, namely sliding control (SC), fixed-frequency quasi-sliding ZAD and PWM-based control have been experimentally tested to highlight the features of the proposed algorithm. According to the experimental results presented in the paper, the ZAD algorithm fulfills the requirement of fixed switching frequency and exhibits similar robustness properties in the presence of perturbations to those of sliding control mode.

As a consequence, for the case of a design requiring , two main constraints affecting the boost output voltage can be highlighted from the previous steady-state analysis, namely, the following.…”

“…Regarding the control subsystem, several control schemes oriented to ensure a proper tracking of an external sinusoidal reference have been suggested. For instance, many tracking control techniques based on high-frequency pulsewidth modulation (PWM) have been proposed in the past for buckbased dc-ac converters [1]- [5]. However, these control strategies are designed by means of a power-stage model, thus leading to output waveforms being sensitive to power stage parameter variations, such as the output load.…”

Abstract-This paper presents a sliding-mode control design of a boost-buck switching converter for a voltage step-up dc-ac conversion without the use of any transformer. This approach combines the step-up/step-down conversion ratio capability of the converter with the robustness properties of sliding-mode control. The proposed control strategy is based on the design of two slidingcontrol laws, one ensuring the control of a full-bridge buck converter for proper dc-ac conversion, and the other one the control a boost converter for guaranteeing a global dc-to-ac voltage step-up ratio. A set of design criteria and a complete design procedure of the sliding-control laws are derived from small-signal analysis and large-signal considerations. The experimental results presented in the paper evidence both the achievement of step-up dc-ac conversion with good accuracy and robustness in front of input voltage and load perturbations, thus validating the proposed approach.Index Terms-boost-buck switching converter, dc-ac step-up conversion, sliding-mode control.
