【Abstract】 An optimized space vector pulse width modulation (SVPWM) algorithm for three-level PWM rectifier is presented, which is well suited for DSP implementation. The reference vector is first transformed into the sixty-degree coordinate system. Then the duration time of the basic vector can be calculated just through some simple arithmetic operations, avoiding the square root and arctangent operation. The simulation results verified the validity of the proposed algorithm.更多还原
