Overlap Generation and Calculation Method
No. 5792-6/7
LB1991V
[Overlap Generation]
Since the voltage generated in the amplitude control block is, taking the center point as the reference, 2
×
<overlap>
×
(1/2 V
S
– V
X
) on one side, the intersection point of the waveform will be <overlap>
×
(1/2 V
S
– V
X
) from the center
point.
To clamp that waveform at (1/2 V
S
– V
X
) referenced to the center point the overlap must be:
A/B
×
100 = <overlap>
×
100 (%).
[Overlap Calculation]

Calculated center point: V
N
= ———————— + V
XL

Since A = V

, B = V
S

, the high side overlap will be:
A

Which can be calculated as:
