Using single phase matrix converter topology a circuit is developed to perform the operations such as step-up cycloconverter, step-down cycloconverter, ac voltage regulator, rectifier, inverter and chopper collectively called as multi-converter circuit. IGBT with antiparallel diode is used as a switching device for controlling current waveform. This paper presents an operation with Symmetrical angle-PWM...
Extraction of respiration rates from electrocardiogram (ECG) and blood pressure (BP) signals would be an alternative approach for obtaining respiration related information. This process is useful in situations when, ECG, or BP but not respiration is routinely monitored or in cases where, the cardiac arrhythmias are to be studied in correlation with respiratory information and is extremely important...
