Output Voltage Waveform
Upper overlap=(2V
α–VA–VXL) / (VA–VXL)×100[%]
Lower overlap=(VA+VXL–2Vβ) / (VA–VXL)×100[%]
1. Upper overlap
DC voltage of upper amplitude : VS–VXH=VA
DC voltage of lower amplitude : VXL
Let the DC voltage at the intersection of two phases of the upper waveform be V
α :
From the drawing shown above
At upper overlap amount=A/B
×100[%]
A =V
α–1/2(VS–VXH+VXL)=Vα–1/2(VA+VXL)
B =(VS–VXH)–1/2(VS–VXH+VXL)=1/2(VA+VXL)
* Upper overlap
=(2V
α–VA–VXL) / (VA–VXL)×100[%]
2. Lower overlap
DC voltage of upper amplitude : VS–VXH=VA
DC voltage of lower amplitude : VXL
Let the DC voltage at the intersection of two phases of the upper waveform be V
β :
From the drawing shown above
At lower overlap amount=C/D
×100[%]
C =1/2(VS–VXH+VXL)–Vβ=1/2(VA+VXL)–Vβ
D =1/2(VS–VXH+VXL)–VXL=1/2(VA–VXL)
* Lower overlap
=(VA–VXL–2Vβ) / (VA–VXL)×100[%]
