摘要： PROBLEM TO BE SOLVED: To solve the problem that although suppliable as AC power output from a power conditioner when a load requiring a large current (e.g., 30 A) is connected to a receptacle for autonomous operation, if a permissible current value of a wiring accessory for autonomous operation (a wiring cable or a receptacle) is 15 A, for example, a current larger than the permissible current may flow into the wiring accessory, resulting in degradation or breakdown of the wiring accessory or occurrence of safety-related abnormality.SOLUTION: By placing an overcurrent breaker in wiring between an AC power output terminal of a power conditioner and a receptacle for autonomous operation, it is possible to prevent a current from continually flowing into a wiring accessory for autonomous operation exceeding its permissible current value even when a load requiring a large current is connected to a receptacle for autonomous operation, because the overcurrent breaker cuts off a current flowing in excess of a prescribed value set for the overcurrent breaker.

摘要： PROBLEM TO BE SOLVED: To obtain a power conversion device that enables a three phase voltage to be balanced even if individual differences occur to component parts of a single-phase inverter and a DC capacitor in each phase. SOLUTION: A balance control circuit 41 of a single-phase inverter DC voltage inputs a voltage detected by a voltage sensor 28 of each phase and a current detected by a current sensor 25 and calculates as a balancing voltage command a voltage command corresponding to a zero-phase voltage component when the single-phase inverters of three phases are considered as a three-phase power source. Then, a voltage command calculation circuit 47 superimposes the zero-phase voltage component on the voltage command of the single-phase inverters 26 of each phase. The zero-phase voltages are the same in each phase, but the phases of currents are different in each phase. Thus, the zero-phase voltage component causes active power to occur to the single-phase inverter 26 of each phase different from each other and a voltage of the DC capacitor 27 of each phase can be changed individually, which balances a voltage of each phase.
