Abstract :
The program Power Electronic Circuit Analysis (PECAN), which has been made to handle some power engineering applications not suited for SPICE or EMTP, is discussed. Time functions of voltages, currents, torque, angular speed, power, and other derived quantities can be calculated and plotted on the screen a printer, or a plotter. The calculations are performed stepwise for a series of points in times, with a variable step size selected by the program within specified limits. Control functions can be converted to equivalent electrical circuits and can be included or studied separately. The program runs under MS-DOS on a personal computer with at least 640 kbytes of memory and a math coprocessor. Input files are provided with the program for many typical problems in power electronics, machine analysis, and others. The program can handle circuits with up to 300 components and 200 variables (nodes plus branches). Examples presented include pulse width modulation (PWM), three-phase diode bridge, symmetrical three-phase short circuit of synchronous generator, and transient temperatures on cables.<>
