While learning 3-Phase scalar control of ACIM using STM32F407 MCU I could not clearly understand the diffrence between the following terms: 1. SPWM 2. 6-step PWM 3. SVMPWM
How do they differ from each other? Do we get the same 3-phase sinusoidals from each of the above PWMs and they are 3 different ways to implement it OR Do they differ in the output that we get from them also? Someone told me that SPWM is used to generate Phase-voltages while the other 2 techniques are used to generate Line-voltages. Is this the only difference between them?
