POWER CONVERSION SYSTEM, POWER CONVERSION SYSTEM CONTROL METHOD, AND PROGRAM

The present disclosure addresses the problem of reducing the impact of power ripples which are caused by an AC power source or by an AC load without using a smoothing capacitor. A power conversion system (10) according to the present disclosure is equipped with a first circuit (1), a second circuit (2) and a third circuit (3). First outside terminals (113, 114) of a first circuit (1) have an AC power source or AC load electrically connected thereto. First inside terminals (111, 112) of the power conversion system (10), second inside terminals (211, 212) thereof and third inside terminals (341, 342) thereof are electrically connected to the same connecting part (8). The second circuit controls the electric current or power of the input to the second circuit (2) or output from the second circuit (2) so as to be synchronized with the power ripple caused by the AC power source or AC load which is electrically connected to the first circuit (1). 本公开解决了在不使用平滑电容器的情况下减少由AC电源或由AC负载引起的功率纹波的影响的问题。根据本公开的电力转换系统(10)包括第一电路(
