The filter coil core was made of Super-MSS™ material [23,42], and the output capacitor was of the Metallized Polypropylene Capacitor MKP type. The transistor switches of the H-bridge were International Rectifier HEXFETs -IRFP 360, which have R DS (on) = 0.20 Ω (@10 A).…”

The aim of this paper is to determine which type of control loop is better for each particular type of standard voltage source inverter (VSI) load (static, dynamic, nonlinear rectifier resistive-capacitive RC load). A comparison of three different types of controllers for single-phase VSIs is presented. The first two are of the single input single output (SISO)/proportional-integral-derivative controller (PID) and coefficient diagram method (CDM) types, and the third is of the multi-input single output (MISO)/passivity-based control (PBC) type. The selections of the gains for SISO and MISO controllers are presented, including the problem in the choice of PBC controller gains caused by the imperfection of the pulse width modulation (PWM) modulator. For a standard nonlinear rectifier RC load, the new control quality factor (CQF) is defined to distinguish the properties of the controllers. The results show the superiority of the MISO-PBC controller for the RC load; however, for a linear dynamic load, the MISO-PBC performed worse than the SISO-PID or CDM. Therefore, the choice between either a simple and inexpensive SISO with one measurement trace or an expensive MISO with three measurement traces depends on the purpose of the VSI. The initial simulations and measurements of the experimental models are presented and discussed.

“…The designing process of the DC/AC converter should start with designing the LC filter (proper C f and L f material selection) and calculating its values [9]. This procedure has a significant influence on the quality of the output voltage v o [9,10]. Nonetheless, switching frequency f c value also has a big impact on the control and system stability.…”

“…Finite-control-set model-predictive control (FCS-MPC), on the other hand, has become a prominent technique for power converter control [7]. It is built on the premise of employing a discrete VSC model with accompanying filter to forecast future behavior for all potential control inputs, and then applying the one that minimizes a programmed cost function (CF) at each sampling time [9]. This technique has been widely and effectively applied to standalone converters due to its flexibility and intrinsically fast reaction.…”

In modern controller design, various solutions for controlling power converter systems can be found depending on their applications, speed of working, pulse width modulation (PWM) techniques, switching frequencies—fc, and different load types. The need to manipulate control parameters can be often observed in classical structures, e.g., well-known PID, repetitive, or deadbeat control particularly sensitive to distinct parameters uncertainties. The purpose of this paper is to present an improved version of controllers designated for a UPS that will be considerably resistant to model changes. Proposed control techniques are independent of unexpected output filter changes: Lf—filter coil inductance and Cf—filter capacitor conductance. The second aspect of this paper is to compare effectiveness of modified predictive MPC (model-predictive control) and feedback PBC (passivity-based control) controllers in reducing output voltage total harmonic distortion (THD) for various load values. The biggest distortions of output voltage were observed during experiments with nonlinear RC load. Both simulation and experimental verification of mismatching parameters were performed and examined. Thanks to the proposed solution, the output voltage THDv quality factor was reduced below 8% in an efficient way for all the applied loads and stayed at the level of 1% when well-matched filter parameters were provided.
