    摘要: An AC system having, for example, a voltage source, an inductance and a load has connected thereto an apparatus for controlling the phase and amplitude of the voltage of the system. The instantaneous current and voltage in the AC electrical system are measured and power measurements derived therefrom. The power measurements may be instantaneous real and imaginary power, instantaneous active and reactive power, or active and reactive power averaged over less than one cycle. The power measurements are then used to derive phase related control values, on the basis of which control signals are generated to a converter. The action of the converter in accordance with the control signals thus controls the amplitude and phase of the voltage. By use of power measurements, it is not necessary to measure the phase of the voltage of the AC system.

    摘要: A fuel cell module of the present invention includes a fuel cell stack and a power converter incorporated respectively in the casing. The power converter has a printed circuit board and a switching semiconductor. The printed circuit board is arranged between the switching semiconductor and the fuel cell stack, thereby cutting off the radiation of heat from the fuel cell stack to the switching semiconductor, and reducing the conduction loss of the switching semiconductor. Further, a high frequency transformer equipped with a Ferrite core is arranged on the side of the fuel cell stack of the printed circuit board, thereby reducing the iron loss in the high frequency transformer.
