    • PROBLEM TO BE SOLVED: To suppress distortion of an AC current at the time of reactive power control.SOLUTION: There is a case where it is required to supply reactive power at a reverse power flow that supplies electric power to an AC power supply, in other words, a system. When doing so, immediately after zero cross of an AC voltage vac, a feedforward control amount FF is given temporarily. The feedforward control amount FF is larger than a feedback control amount FB calculated at the same time. In response to the feedforward control amount FF, a reactor current iL sharply increases immediately after the zero cross. Then, in response to the feedback control amount FB, the reactor current iL is controlled smoothly. By means of the feedforward control amount FF, a control delay by the feedback control amount FB is compensated for. As a result, an Ac current iac changes smoothly, so distortion of the AC current iac is suppressed.
    • 要解决的问题:为了抑制无功功率控制时的交流电流的变形。解决方案:需要以向AC电源供电的反向电力供给无功功率的情况下, 换句话说,一个系统。 当这样做时,紧接着交流电压vac的零交叉之后,暂时给出前馈控制量FF。 前馈控制量FF大于同时计算的反馈控制量FB。 响应于前馈控制量FF,电抗器电流iL在零交叉之后立即急剧增加。 然后,响应于反馈控制量FB,平稳地控制电抗器电流iL。 通过前馈控制量FF,补偿反馈控制量FB的控制延迟。 结果,交流电流iac变化平滑,因此抑制了交流电流iac的失真。

    • PROBLEM TO BE SOLVED: To provide a pressure control means for controlling the temperature and the pressure on the side of a radiator outlet such that a vapor pressure compression type refrigerating cycle working in a super-critical area is efficiently operated.
      SOLUTION: A refrigerant is enclosed in an enclosed space 12 such that, with respect to the volume in the sealed space 12 with a valve port 17 closed, a density of the refrigerant is in a range between a density of a saturated liquid at a temperature of 0°C and a density at the critical point of the refrigerant. As a result, the pressure at the outlet side of the radiator 2 and the temperature at the outlet side of the radiator 2 are controlled substantially along the optimum control line ηmax. Thereby, a CO
      2 cycle can efficiently be operated even in a super-critical area.
