The pulse-width modulation (PWM) pulse signal output end of the converter/ inverter is connected with the input end of the IGBT module though a first shielding line, the PWM pulse signal output end connected with the input end of the IGBT module is further connected with one end of a ...
This paper presents an analytical approach for determining the spectral components of multilevel pulsewidth modulation (PWM) strategies, which avoids the p... McGrath, B.P.,Holmes, D.G. - 《IEEE Transactions on Industrial Electronics》 被引量: 121发表: 2002年 ...
A particular application of this measuring system is in the measurement of the temperature of living bodies wherein the changes in temperature are transmitted via a pulse width modulation telemetry system to a receiver incorporating the measuring system. By means of continually up-dating the reference...
摘要: PROBLEM TO BE SOLVED: To obtain a highly accurate result of measurement of a pulse width by a low-frequency clock without using a high-frequency clock or the like, by providing first and second comparators and a reference waveform generator....
This signal (s) is from the signal by pulse width modulation (pwm) of one sensor (2, 16) and described as from the signal (pam) of the other sensor (1, 15) of the drawings: fig. A receiver device (6, 27), on the input side, via a line connection (5, 26) with the ...
1. A method for measuring phase currents in an inverter where by pulse width modulation controlled semiconductor switches invert direct voltage from an intermediate circuit into a threephase alternating voltage, and where the phase currents are measured by measuring the intermediate circuit current when...
Devices that always operate in continuous-conduction or pulse- width-modulation (PWM) mode draw DC currents from the input supply. Unlike the DC current drawn in PWM mode, the power-save mode's bursts of current create an incorrect RMS-current reading in the input-current meter. Therefore, ...
