摘要： PROBLEM TO BE SOLVED: To provide a system linkage inverter controllable even in a region exceeding the maximum point of the output. SOLUTION: An output current command value arithmetic means 13 inputs a DC power from an input power source 1, converts the power into an AC power and calculates an output current command value for obtaining an output current io of a sine wave with an inverting operation of a booster converter 3 and an inverter 5 when outputting the AC power to a power system 2, and calculates the command value based on the input voltage. The means 13 calculates the command value based on the input voltage normalized from the input voltage Vin from the power source 1 by the normalized voltage as a reference, that is, input voltage/normalized voltage, and gives the calculated value to a control means 9. Thus, the means 13 can output the output current command value even in the region exceeding the maximum power point to be controllable, and can follow the maximum point. When a solar cell is used as the input power source 1, as the normalized voltage, its open circuit voltage or more can be set.

摘要： PROBLEM TO BE SOLVED: To conduct highly efficient heating and manage not to damage a soft feel to eating by performing cooking with superheated steam having good heating efficiency. SOLUTION: A superheated steam generating means 6 generates superheated steam in accordance with the outputs from a cooking control means 7 and a plane heater 3 heats a heating box walls in accordance with the outputs from the cooking control means 7. When the generated steam temperature is high, electric energy is increased by an electric control means and the flow rate of water is reduced, and therefore water is heated more rapidly and the steam is heated to have much higher temperature. When the superheated steam collides with low temperature objects and alters to water, latent heat is given to the objects to transfer temperature thereto. The heating box 1 is heated in order to prevent the superheated steam from altering to water when collided with the heating box walls. The heating box walls are heated by the plane heater 3 to not less than 100 deg.C to efficiently heat food. Superheated steam of less than 120 deg.C is appropriate for steam cooking and that of not less than 120 deg.C is appropriate for roast cooking.

摘要： PROBLEM TO BE SOLVED: To provide a system interconnection inverter which can accurately form waveform of an output current, even if changes occur in the input voltage to the inverter and in the system voltage. SOLUTION: The high-frequency switching of a switching element of an inverter 5 is controlled, so that the upper limit and lower limit of the command value are generated in the predetermined hysteresis width for the command value forming the waveform of an output current is with a command value upper limit generating means 13 an a command value lower limit generating means 14, and an output reactor current of an output reactor 6a detected with an output reactor current detecting means 12 is maintained between the command value upper limit and command value lower limit. When the output reactor current becomes lower than the command value lower limit, a switching element Q1 is turned on and the switching element Q2 is turned off. When such an output reactor current exceeds the command value upper limit, the switching element Q1 is turned off, while the Q2 is turned on. The output reactor current takes values between the command upper limit and lower limit, and the average current thereof becomes an output, current depending on the command value.
