Oscillation margin
WebHowever, when the PLL phase margin is greater than a certain value, the system will enter a supersynchronous oscillation mode, which can cause a supersynchronous oscillation. Thus, to suppress the sub/super-synchronous oscillations of the grid-connected inverter under weak grid, the phase margin of PLL should neither be too small nor too large. WebDrive level could be calculated as follows. Drive level = I 2 ･R1. I: Drive current [Effective value] R1: Equivalent series resistance of crystal unit. Drive current is a current through crystal unit while the oscillation circuit works. Drive current could be measured on actual oscillation circuit.
