In this paper, a novel high frequency transformer linked full-bridge type soft-switching phase-shift PWM control scheme DC-DC power converter is presented. A tapped inductor filter is implemented in the proposed soft-switching converter topology to achieve wide load variation range soft-switching PWM constant frequency operation of the DC-DC converter, to minimize circulating current. The presented converter operates with ZVS for leading bridge leg active power switches due to lossless snubber capacitors, and ZCS for lagging bridge leg active power switches with the aid of the high frequency transformer parasitic leakage inductance component and tapped inductor filter. The effectiveness of the proposed soft-switching DC-DC converter is verified in experiment with 2 kW 100 kHz breadboard setup using IGBTs. Actual efficiency of 94% is obtained for the wide load variation range.

In this paper different open loop PWM control techniques for multilevel voltage source inverters are investigated and compared. For sinusoidal PWM control, a comparison between different carrier techniques with different modulating signals is performed. This comparison includes total harmonic distortion and distortion factor of the phase and line voltages. A comparison between different modulating signals in sinusoidal PWM (pure sinusoidal, third harmonic injection, and dead band), space vector modulation, and sigma-delta modulation is performed. This comparison includes total harmonic distortion, distortion factor, fundamental, and harmonic RMS of the line voltage.

The effects of linear imbalances and nonlinear loads on the voltage balance of the neutral-point-clamped converter are described in this paper. The study reveals that a negative sequence of output currents (linear imbalance) may produce additional low-frequency oscillations to the neutral-point voltage. Similar consequences are produced by odd-order current harmonics from a nonlinear load, while even-order harmonics can cause the neutral-point voltage to shift. Furthermore, the second, fourth and eighth output current harmonics might produce instability to the neutral-point voltage. The second and fourth harmonics are the worst components. The maximum amplitudes of these harmonics superposed to the current fundamentals that the system can tolerate are described. Simulated and experimental examples are presented.

The paper present a fully digital control of single-phase boost power factor preregulators (PFPs) based on inductor (or switch) current and output voltage measurements. Input voltage sensing is avoided using a disturbance observer, which provides a waveform proportional to the rectified input voltage. The proposed solution is based on a multiloop structure for PFP with an internal deadbeat current control and an outer voltage control with fast dynamic response. The resulting control algorithm is simple, accurate and robust respect to parameter mismatch. The digital control has been implemented both in a field programmable gate array (FPGA) and in a DSP (TMS320F2812), so as to test the proposed algorithm with different control delays. Experimental results on a single-phase 500 W boost PFP show the effectiveness of the proposed solution.

The series compensator is a challenging solution for power quality problems related to the voltage. One of the most common control algorithms used for the series voltage compensator is the symmetrical component method. this paper introduces a new recursive least square (RLS) structure for symmetrical components estimation. This structure is capable of dealing with multioutput (MO) systems for parameter estimation and is called MO-RLS. A novel feed forward control based on the proposed MO-RLS is dictated for the series compensator not only to compensate for the zero and negative sequence components, but also to regulate the positive sequence component to the nominal load voltage. One advantage of the proposed control system is its insensitivity to parameters variation, a necessity for the series compensator. Simulations of the proposed algorithm are conducted to show the robustness, the high accuracy and the fast dynamic performance of the novel system.

3D circuit animations can be highly effective to understand and to visualize the interactions of components, voltages and currents in power electronics. With modern computer hardware and software tools, animations can be readily produced, and have been used to demonstrate power electronic circuit behavior. We introduce a new circuit animation system and the ideas behind it to the power electronics community. This animation system, offers potentially important advantages in showing the interactions of components, voltages, and currents in power-electronics circuits. We apply it to develop animations of rectifiers and DC/DC converters, and we report experience using them in a power electronics course.

Pulsewidth modulated voltage source inverter can be easily controlled in such a way as to achieve the desired value of the output voltage and/or current, but they exhibit high switching losses when operated at high switching frequencies. Besides, relevant electromagnetic interferences can be produced because of the high di/dt and dv/dt in the converter waveforms. These problems can be partially or totally eliminated if the converter switches are commutated at zero voltage and/or zero current. This is achieved by means of suitable tuned LC resonant circuits. In this paper, a novel topology of quasi-resonant DC link for soft switching of VSI is proposed. It is based on two resonant circuits: a main one, which makes the voltage oscillating around the main DC bus voltage, and which is commutated at zero current, and an auxiliary circuit which is enabled to drive the DC voltage to zero just when an inverter switch commutation occurs. Dead time imposition is fully taken into account. A detailed experiment investigation has been performed for validating the proposed scheme.

The paper presents detailed analysis of the synchronized overmodulation control modes for three-level neutral-clamped inverters with control algorithms which eliminate the common-mode voltages. Two basic versions of discontinuous pulsewidth modulation (PWM) for control of inverters in the zone of overmodulation have been analysed in the paper. The spectra of the output voltage of inverters do not contain even harmonics and sub-harmonics (combined harmonics) in the overmodulation zone, which is especially important for the medium- and high-power systems. Simulations show, that linearity of the fundamental voltage during overmodulation is much better for the algebraic algorithms of synchronized PWM in comparison with the trigonometric ones.

The conception of power electronics converters is made without a real EMI prediction method. The classical sizing methods based on experiments are effective but not optimized. They involve the increase in the designing duration and generally lead to the oversize of the filter. To reduce these stages, a mathematical model for the prediction of conducted EMI generated by a three-phase inverter is pointed out in this paper. This model, based on analytical disturbance-sources and propagation paths, including EMI filter and the induction motor, permits the estimation of common and differential modes in all the structure. Passive components and especially the filter elements have been modeled. With this method, the effect of different filter components can be evaluated by simulations. Time domain and frequency simulations are compared and discussed.

This paper describes a new SiC-based motor drive technology used to achieve compact power conversion. The static and dynamic characterization of 600 V SiC MOS-enhanced JFETs and SiC Schottky free-wheeling diodes (FWDs) designed and fabricated at Rockwell Scientific, are performed. Single 5 A SiC JFET and Schottky FWD die with a voltage rating of 600 V are paralleled to obtain 10 A, and 25 A, current ratings. The power loss and related voltage and current stress of the SiC MOS-enhanced JFET and SiC Schottky FWD are measured and compared to that of a state-of-the-art silicon IGBTs and PIN FWDs with ratings equal to the SiC ratings. For the same power rating (25 A, 600 V), the area of the SiC die making up the inverter module are about 60% of a commercial 25 A IGBT die. The Rockwell Automation RA Model 1336 motor controller is used, with its gate drive circuit modified to control the SiC depletion-mode MOS-enhanced JFETs, to control a motor. SiC inverter modules are fabricated and used to successfully drive 1 hp to 10 hp motors. To our knowledge, this is the first time that a motor drive using SiC inverter modules has been demonstrated.
