Description
(式1)・・・F0(Φ)=n×(180°×f)/Φ (nは1以上の整数で奇数)
また、合成高調波が大きくなる周波数FP(Φ)は、下記の式で表すことができる。
(式2)・・・FP(Φ)=m×(180°×f)/Φ (mは2以上の整数で偶数)
一方、2つのPWM駆動信号の周波数をf、デューティ比の差をDとすると、2つのPWM駆動信号のそれぞれの高調波を合成した合成高調波がゼロとなる周波数F0(D)は、下記の式で表すことができる。
(式3)・・・F0(D)=n×(100%×f)/D (nは1以上の整数で奇数)
また、合成高調波が大きくなる周波数FPは、下記の式で表すことができる。
(式4)・・・FP(D)=m×(100%×f)/D (mは2以上の整数で偶数)
ここで、位相およびデューティ比の双方を調整して高調波ノイズを低減させることを考えると、(式1)=(式4)、または(式2)=(式3)となる条件が満たすことができれば、合成高調波成分を効率的に相殺することができる。
(式5)・・・Φ=1.8×(m/n)×D 図2に上記の関係を備えたPWM駆動信号AおよびPWM駆動信号Bを示す。
