  "textContent": "A power compensation control method and apparatus for a high-power multi-functional efficient charging system. A topology structure of the charging system includes at least two parallel high frequency link matrix converters. The power compensation control method includes: calculating a difference between an input voltage phase of an iconverter and an ideal reference input current phase under a dq two-phase synchronous rotating coordinate system, where i is an odd number; calculating, according to the above difference, a required rotating phase angle of a space current vector of an (i+1)converter, where by total instantaneous reactive power at input sides of the iconverter and the (i+1)converter is zero; correspondingly rotating the vector, and judging a sector to which the rotated vector belongs; and generating a corresponding control pulse signal based on the corresponding sector and modulation ratio, so as to act on the (i+1)converter to realize power compensation.",
