“…PWM methods for three-phase Voltage Source Inverters (VSIs) can be divided into two categories, the methods for the output current control which are mostly closed loop methods and the schemes for output voltage control whose switching action does not depend on output voltage feedback information and are open loop methods [1], [2]. Closed loop methods such as Sliding Mode based PWM for current control [2], hysteresis and predictive current control [3]. Open loop methods such as sinusoidal and Space Vector PWM methods [4].…”

“…Hence it is reasonable to employ SMC concept, resulting in a discontinuous control law, as an effective replacement for the conventional PWM techniques for the voltage or current control of power converters [5], [6]. In [2] a sliding mode based PWM method is proposed for the current control of a VSI in a closed loop manner. In the proposed method, the average voltage of the neutral point of a star connected load is also controlled as an extra degree of freedom.…”

“…Unfortunately, the mathematical details have not been presented. In this paper, the proposed method in [2] for the neutral point voltage control is developed for the control of the output three-phase voltage of an VSI in an open loop manner. Since the proposed PWM has a variable frequency, its maximum frequency has to be limited and known.…”

In this paper, a Sliding Mode Control (SMC) based Pulse Width Modulation (PWM) method is proposed for the voltage control of a three-phase Voltage Source Inverter (VSI). This variable frequency PWM method is designed such that the average of the outputs, i.e., the three-phase voltage of VSI and the neutral point voltage of a star connected load, track the desired references. A suitable mathematical model of VSI is derived. Because of the control objective which is the tracking of a desired reference by the average of discontinuous output, some integral sliding surfaces are defined. Based on the mathematical model and the defined sliding surfaces, a controller is designed to generate suitable signals for the gates of the VSI switches. Simulation results verify the satisfactory performance of the proposed method.

Comparative Study of Discrete PI and PR Controls for Single-Phase UPS Inverter

This paper presents a comparative study of discrete proportional integral (PI) and proportional resonant (PR) current control for single-phase uninterruptible power supply (UPS) inverters. There is an increasing requirement for current and voltage-controlled UPS inverters with very low or zero steady-state error, improved transient response and lower total harmonic distortion (THD). The most promising type of current regulator for single-phase inverters is PR control because it can introduce an infinite gain at a selected resonance frequency such as the fundamental frequency to eliminate the steady-state error, which cannot be achieved by well-known proportional integral (PI) control. Note that PI control has limitations in terms of the steady-state magnitude and phase errors. In addition, PI control also has limited harmonic rejection capability, unlike the PR control, also can compensate for low-order harmonics. Imperfections in the current and voltage control scheme results in higher harmonic distortion of the output current and voltage. In this paper, performance of PR control parameters (K p , K i , and ω c) and filter parameters (L f and C f) are optimally tuned to obtain a very low THD current with reduced output voltage ripple and steady-state error. The analysis, design and implementation of both PI and PR current control in single-phase UPS inverter applications through simulations and experiments are also presented in this paper. The performance of both of these control schemes are analyzed in terms of steady-state response, transient response, and level of current harmonics. INDEX TERMS Proportional-integral (PI) control, proportional-resonant (PR) control, linear control, non-linear control, uninterruptible power supply (UPS), single-phase inverter, total harmonic distortion (THD).
