Novel asymmetric duty modulation for DAB converters to …
nal phase-shift angle of the primary side, and DPS control was formed by simultaneously increasing the internal phase-shift angle of the primary and secondary sides. To further improve DAB performance, a triple phase-shift (TPS) con-trol that can control the inner and outer phase-shift angles of the primary and secondary sides was proposed in [12].
The conclusion is that, in this arrangement, the phase shift varies from zero to 90 degree when the frequency varies from zero to infinity because of the imperfect input current source that cannot compensate the voltage drop (losses) across the capacitor. These explanations are based on an old Wikipedia discussion.
Simplified Guide: Wiring a Baldor Single Phase Motor with Capacitor

As a capacitor can constitute a leading phase shift the capacitor bank compensates for the lagging phase shift of the inductive reactance; the leading current counteracts the lagging current. Thereby it maintains a unity power flow by reducing the overall phase shift and the reactive component when connected in parallel with the load.
Primarily, a larger capacitor value increases the phase shift between the start winding and the main winding in the fan motor. This increased phase shift results in higher starting torque, which can help the fan start more easily and quickly, especially under load or when operating conditions are less than ideal.
What is the function of capacitor in an electric pump
