摘　　要：空间矢量调制(SVPWM)在多电平逆变器的控制中应用广泛,但是随着电平数增加控制算法渐趋复杂化。文中提出的三电平SVPWM控制方法,将三电平电压矢量区变换为由两电平空间矢量区构成,从而通过使用两电平SVP-WM调制方法简化了控制算法。该方法理论上可应用于更高电平逆变器的控制中。仿真验证了方法的可行性。Space-vector PWM has been used widely in control of multi-level inverters, but the control arithmetic will be more complicated as the number of level increases. This paper presents a kind of SVPWM that can use two-level SVPWM to simplify arithmetic through converting three-level reference voltage and can be used in multi - level SVPWM above three level. The simulation results prove the feasibility of given control arithmetic.
