Most such loads, including motor drives, computer power supplies, and even compact fluorescent lighting \"isolate\" the load dynamics from the utility grid. When isolated these loads enforce local constant power behavior, which can de-stabilize a weak power system. One method to mitigate the effects of constant power loads is the use of active dynamic power buffers. This paper reviews the power buffer concept, and presents DC-DC converter control methods and considerations to implement an active power buffer.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

The inverter was designed for a maximum pack voltage of 200 V and minimum operating frequency of 6.67 kHz while operating in the continuous conduction mode. It uses a pair of insulated gate bipolar transistors (IGBTs) connected in a half bridge configuration. The inverter circuit was first simulated in PSpice for obtaining adequate values for the circuit components and then constructed. A digital circuit was used to control the input signals to the IGBT driver cards. The inverter was tested on a pack of nickel metal hydride (NiMH) batteries at different cold temperatures to verify the feasibility of high frequency AC heating. A sophisticated data acquisition system was used for measuring battery temperature and voltage data for display on a computer. This data was also used to control the inverter operation during the tests. Experimental results have shown that at both -20 and -30 /spl deg/C, 10-20 kHz AC currents at amplitudes of 60-80 A rms warmed the pack to about 25 /spl deg/C within a few minutes, and thereby improved the pack discharge capability.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

Generally, the time-domain modeling of magnetic devices is completed by solving a high order system at each time step. Fortunately, the full order state-space models can be reduced methodically without additional assumption. The method for reducing the order of magnetically linear system is presented in previous work. However, in the analysis of magnetic devices the problems are usually nonlinear due to the presence of ferromagnetic materials. In this paper, a nonlinear model of the magnetic devices is presented and reduced by using a trajectory piecewise-linear approach.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

First, the multilevel converter is decoupled into unipolar converters, the low order harmonics, such as the 5th, 7th, 11th and 13th are eliminated by using elimination theory, and the minimum THD combination of unipolar converters for multilevel converter control is found. Next, the magnitudes and phases of the residual higher harmonics are computed and subtracted from the original output voltage waveform to eliminate these higher harmonics. To validate the proposed algorithm, the method is simulated by Matlab first. After the simulation, an experimental 11-level H-bridge multilevel converter with a real-time controller based on Altera FLEX 10 K field programmable gate array (FPGA) is used to implement the algorithm with 8 /spl mu/s control resolution. The experimental results show that the method can effectively eliminate the specific harmonics as expected, and the output voltage waveforms have low THD.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

SiC JFETs are power switches that have a variety of applications in the industry. A compact model is developed in VHDL-AMS based on the device geometry and SiC material properties.
