Inverter controlling method, involves producing signal that corresponds to sinusoidal signal with amplitude amount after demodulation, where amplitude amount is different from another amount, and coupling signal behind another signal

摘要

The method involves producing a signal by a sequence of rectangular impulses (T1-Tx) of variable pulse duration (u1-ux), where the signal corresponds to a sinusoidal signal with amplitude amount (A2). Another signal (S2) is produced with the preset period by a sequence of rectangular impulses (Tx plus 1-TM) of variable pulse duration (ux plus 1-uM), where the latter signal corresponds to a sinusoidal signal with another amplitude amount (A3) after demodulation. The latter amount is different from the former amount. The latter signal is coupled temporally behind the former signal.
