Function GMCLIB_SvmStd_F32<br />

Equation GMCLIB_SvmStd_Eq10<br />

where T 120 <strong>and</strong> T 60 are the respective duty-cycle ratios <strong>for</strong> which the basic space vectors<br />

U 120 <strong>and</strong> U 60 should be applied within the time period T. These resultant duty-cycle<br />

ratios are <strong>for</strong>med from the auxiliary components termed A <strong>and</strong> B. The graphical<br />

representation of the auxiliary components is shown in Figure 4-54.<br />

Figure 4-54. Detail of the voltage vector projection in sector II<br />

The equations describing those auxiliary time-duration components are:<br />
