交直交型變頻器的spwm工作過程？

把正弦半波分成N等份，就可以把正弦半波看成是由N個(gè)彼此相連的脈沖序列所組成的波形。

這些脈沖寬度相等，都等于 /N，但幅值不等，且脈沖頂部不是水平直線，而是曲線，各脈沖的幅值按正弦規(guī)律變化。如果把上述脈沖序列利用相同數(shù)量的等幅而不等寬的矩形脈沖代替，使矩形脈沖和相應(yīng)正弦波部分的中點(diǎn)重合，且使矩形脈沖和相應(yīng)的正弦波部分面積（沖量）相等，就得到脈沖序列,這就是PWM波形。可以看出各脈沖的幅值相等，而寬度是按正弦波規(guī)律變化的。根據(jù)面積等效原理，PWM波形和正弦半波是等效的。對(duì)于正弦波的負(fù)半周，也可以用同樣的方法得到PWM波形。像這種脈沖的寬度按正弦規(guī)律變化而和正弦波等效的PWM波形，也稱SPWM（Sinusoidal PWM）波形。要改變等效輸出的正弦波的幅值時(shí)，只要按照同一比例系數(shù)改變上述各脈沖的寬度即可。

peak to peak 電壓

peak to peak 電壓 :峰峰電壓,指最大和最小之間的電壓差.

10v sinusoidal supply,一般是指有效值為10v,不等于峰峰電壓.

峰值電壓=根號(hào)2*有效值=1.414*有效值.

峰峰值=最大-最小

正弦對(duì)稱電壓中,最大為最高峰值為正電壓,最小為最低峰值為負(fù)電壓,所以峰峰值=峰值*2=1.414*有效值*2=2.828*有效值

所以10v sinusoidal supply,peak to peak 電壓為2.828*10=28.28V
