When static, Vi- oV, the midpoint voltage VD V +/2, B-point voltage VB VD V +/2, A point voltage hoot v + a VR, the bootstrap capacitor c is A, is charged between B, charging voltage V VA - VB v bucket. A VR + -V/2 v +/VR 2, VR is negligibly small due. When C is large, even if the AC signal voltage by too, the charge voltage V +/2 does not change.
