摘要
SVPWM是"电力电子技术"教学中的重要内容,SVPWM教学中存在若干难点,其中突出的是,SVPWM的理论基础在现有教材中没有提及。本文在证明冲量等效原理的基础上,将其推广到三线三相等效电路的线电压冲量等效原理,从而证明了SVPWM的理论基础,即空间矢量的冲量等效原理,从而有助于学生透彻理解SVPWM。
SVPWM is an important content in Power Electronic Technology teaching.There are some difficulties in SVPWM teaching,among which the theoretical basis of SVPWM is not mentioned in the existing textbooks.On the basis of proving the impulse equivalent principle,this paper extends it to the line voltage impulse equivalent principle of three wire three-phase equivalent circuit,thus proving the theoretical basis of SVPWM,namely the impulse equivalent principle of space vector,so as to help students understand SVPWM thoroughly.
