52 / 105 page ![]() Library functions UM0324 52/105 4.3 Isolated current sensor reading and space vector PWM generation: 75x_svpwm_ICS module 4.3.1 Overview Two important tasks are performed in the 75x_svpwm_ICS module. ● Space vector pulse width modulation (SVPWM), ● Three-phase current reading when two isolated current sensors (ICS) are used. In order to reconstruct the currents flowing through a three phase load with the required accuracy using two ICS’, it is necessary to properly synchronize A/D conversions with the generated PWM signals. This is why the two tasks are included in a single software module. 4.3.2 List of available functions and interrupt service routines The following is a list of available functions as listed in the 75x_svpwm_ICS.h header file: ● SVPWM_IcsInit on page 53 ● SVPWM_IcsCurrentReadingCalibration on page 53 ● SVPWM_IcsGetPhaseCurrentValues on page 54 ● SVPWM_IcsCalcDutyCycles on page 54 |
