A hybrid phase modulated converter (HPMC) with current doubler rectification has superior soft switching characteristics, high efficiency, and low EMI as compared to a conventional phase modulated converter. It has essentially three modes of operation: (i) continuous conduction mode (CCM); (ii) continuous conduction mode with reversed inductor currents; and (iii) discontinuous conduction mode (DCM). There is never a discontinuity in conduction in the inductors and the definition of DCM is different in itself. In this paper, the various modes are defined, analyzed and design equations derived. The analyses are also verified with a 500 W peak current mode controlled prototype model, switched at 100 kHz and the results are presented. The soft switching behavior of the converter in this mode is also studied and is found to be advantageous.

In a UPS, the output voltage of a single-phase inverter is filtered with an LC filter to provide a sinusoidal output voltage. Since this inverter has an inductive load like an inverter for a motor drive, topologies for ZVS inverters utilized for motor drives can also be applied in the UPS application. A single-phase resonant snubber inverter (RSI) for application in a UPS has been developed. Analysis of the RSI in a normalized state plane provided insight into the operation of this ZVS inverter. Based on this analysis, fixed timing control based on the direction of the current flowing through the inductor in the output filter was implemented to control the auxiliary switches in a prototype RSI. The direction of the inductor current was sensed using a secondary winding on the output filter inductor. Experimental results are provided for a 1 kW prototype RSI in a UPS.

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.

In this paper an approach to improve battery run-time in mobile applications with supercapacitors is explored. The performance of a battery-supercapacitor combination is analytically described using simplified equivalent circuit models. It is shown that there is an overall reduction in the internal losses and this translates into increased run-time. Three possible approaches are explored: (a) supercapacitors connected directly across the battery; (b) battery-inductor-supercapacitor connection; and (c) supercapacitor, and battery connected via a DC-DC converter. Analytical models, simulation and experimental results on a typical laptop computer are presented. These results show an increase in runtime of 4-12% is achievable. Also from these results it is shown that the use of a DC-DC converter appears to be a cost effective option, since it allows the use of reduced number of capacitors while maintaining a comparable performance.

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.

Shunt active power filters are proved a useful elements to correct the distorted currents caused by nonlinear loads in power distribution systems. This work presents an all digital approach, based on the repetitive control technique, for their control and a design is performed for the particular case of single-phase shunt active filters with a full-bridge boost topology. Several experimental results are also presented to show the behavior of the closed loop system.

This paper presents a hybrid compensation system consisting of an active filter and distributed passive filters. In the system, each individual passive filter connected to a distortion source is designed to eliminate main harmonics and supply reactive power for the distortion source, while the active filter is responsible for the correction of the system unbalance and the cancellation of the remaining harmonics. The studies are presented for a power system including dispersed generation units connected into systems through power electronic converters and diode rectifier loads, which generate distorted waveforms. The simulation results have demonstrated that good compensation effects can be achieved by using the combined filter system including distributed passive filters and an active filter.

In this paper, a new three-phase high-frequency link matrix converter is discussed and the topology of conventional matrix converter is modified with the addition of a transformer for a variable speed constant frequency (VSCF) application. The proposed approach accomplishes voltage transfer ratio more than unity, galvanic isolation between both voltage sources and higher power density by employing a high-frequency transformer into the intermediate stage of the dual bridge matrix converter. It has a bidirectional power flow capability, controllable displacement power factor and lower harmonic distortion at both variable speed source and fixed frequency utility. Further, asynchronous or synchronous PWM can be employed depending on the frequency modulation ratio in the primary side converter and it guarantees full input voltage utilization for DC-link and near symmetric square wave pulse trains applied to high frequency transformer regardless of varying input frequency. The proposed approach is a competitive solution for VSCF distributed generating application such as wind-turbine and micro-turbine application. Simulation results are shown to demonstrate the advantages of the proposed system. Experimental results on a 230V, 3kVA 400 Hz to 60 Hz VSCF system based on DSP controller are presented.

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.

A method to automatically create low order state-space models for magnetic devices is set forth. The method begins with geometrical and materials data from which the finite element analysis is used to build a high order state-space model. It is shown that this model, while accurate within the tolerance of the material properties data, contains far more state variables than are necessary to achieve such accuracy. It is shown that the full-order model can be reduced methodically without additional assumptions. The method is applicable directly to magnetically linear systems, but applies to a wide range of power electronics applications and can be a basis for future nonlinear device modeling. The method reduced an example inductor model from 882 state variables to two and is verified experimentally.
