In special cases where this process occurs frequently (for example, elevator motor control systems), it is economical to incorporate special features in the motor drive to allow this energy to be supplied back to the ac mains. Hi again. I made a printed circuit board for this circuit. Look at the trailing edges of In4 and in5 and use these trailing edges to trigger the start points of Out2 and Out3 so generating the required phase lags on these pair of outputs. Theres another possibility, too: we drive only two windings at a time and leave the third one open so no current is flowing through it and no magnetic force is generated, but that requires using 6 I/O pins and 6 discrete transistors. Add yourself by clicking here! This always gives square waves (0 or 5 V) so I think the problem of unpredictable results at the output wont be a question. Can this change at the input give you a sin wave at the output with your setup? I Hope can understand my questions. The Rar archive contains photos, gerber files, drill files and BOM sheet. In this post we learn how to make a simple microprocessor Arduino based 3 phase inverter circuit which could be upgraded as per user preference for operating a given 3 phase load.
