This paper introduces the topology of active power filter (APF) with three-level diode clamped and its principle. the paper analyses the space vector PWM (SVPWM) principle in detail. The traditional SVPWM algorithm requires a lot of calculation about trigonometric functions, and it needs to judge the sector. This paper studies a SVPWM algorithm based on 60° coordinate. This algorithm omits the sector...
