Overlap Generation
Since the voltage generated in the amplitude control block is, taking the center point as the reference, 2
× <overlap> ×
(1/2 VS − VX) on one side, the intersection point of the waveform will be <overlap> × (1/2 VS − VX) from the center
point.
To clamp that waveform at (1/2 VS − VX) referenced to the center point the overlap must be:
A/B
× 100 = <overlap> × 100 (%).
Overlap Calculation
• Upper side overlap
Calculated center point: VN =
(VS − VXH − VXL)
2
+ VXL =
(VS − VXH + VXL)
2
Since A = V
α − VN, B = VS − VXH − VN, the upper side overlap will be:
<overlap> =
A
B
=
V
α − ((VS − VXH + VXL)/2)
VS − VXH − ((VS − VXH + VXL)/2)
×100
Which can be calculated as:
=
2V
α − (VS − VXH) − VXL
(VS − VXH) − VXL
×100(%)
• Lower side overlap
Since C = VN − Vβ, and D = VN − VXL, the lower side overlap will be:
<overlap> =
C
D
=
((VS − VXH + VXL)/2) − Vβ
((VS − VXH + VXL)/2) − VXL
×100
Which can be calculated as:
=
(VS − VXH) + VXL − 2Vβ
(VS − VXH) − VXL
×100(%)
