PROBLEM TO BE SOLVED: To stabilize a current, regenerated to a power system, with a simple configuration and irrespective of a system voltage and a waveform distortion in an inverter by which output power from a DC power supply such as a solar cell or the like is supplied to an AC load such as the power system, a motor or the like. SOLUTION: A high-frequency voltage source which is composed of a solar cell 12 and of a PWM inverter 14 is converted into a high-frequency current source by means of an immittance converter 15, and a desired constant current Is can be supplied by a voltage control operation irrespective of a system voltage Vs and irrespective of the waveform distortion of the system voltage Vs . Thereby, it is possible to obtain an inverter in which a large-scale configuration such as a linkage reactor or the like is not required, in which it is not required to perform a complicated control operation, whose configuration is simple, which is not subjected to a change in the system voltage Vs , which is not affected even with reference to the waveform distortion of the voltage Vs and which can always regenerate a desired constant current Is . |
