Zusammenfassung:	A power conversion system with ripple injection includes an AC-DC conversion unit, a voltage stabilization unit, a DC-DC conversion unit, at least one load and a first control unit. The AC-DC conversion unit has a first input side and a first output side, and the first input side receives an AC power supply and provides input power. The voltage stabilizing unit is coupled to the first output side, provides a direct current chain, and receives a part of input power as energy storage power. The at least one DC-DC conversion unit is provided with a second input side and a second output side, the second input side is coupled with the DC chain, and the other part of input power is received as output power. The at least one load is coupled to the second output side and receives power supplied by the output power. The first control unit is coupled to the DC chain, the at least one DC-DC conversion unit and the at least one load. The first control unit controls the at least one DC-DC conversion unit to adjust the rip
