Fault ride through (FRT) ability is indispensable for the power conditioners connected to the ac utility system. The power conditioner of the photovoltaic system in Japan is required to remain connected when the utility power system fault occurs under certain condition. The most popular fault is 1 line-to-ground fault and the next is 2 line-short fault. Both cause the imbalance voltages and currents...
This paper proposes a real time symmetrical coordinate transformation applied for detection of imbalanced fault in utility power system. The power conditioner of the photovoltaic system in Japan is required to remain connected when the utility power system fault occurs under certain condition. The most popular fault is 1 line-to-ground fault. The next is 2 line-short fault. Both cause the imbalance...
This paper has investigated the possibility of a real time symmetrical coordinate transformation. Simulation is performed when it is applied for detection of imbalanced fault in utility power system. The power conditioner is required to remain connected when the fault occurs in the utility power system under certain condition. This is called as the fault ride through (FRT) ability. The most popular...

This paper presents the possibility to make the dc current ripple to zero. The simulation results show that the ripple-less operation is possible theoretically. The fast response in the current control is also shown by using the simple digital control algorithm. The control for the load change is investigated in simulation. The simulation results show that the output current loop is more suitable...
This paper proposes the new simple current measurement method. It utilizes the voltage measurement of the MOS-FET switching device at the dc-dc converter to measure the current instead of conventional measuring methods, such as the DC-CT or the shunt resistance. The precise measurement is not necessary to perform the Maximum Power Point Tracking (MPPT) control of dc energy source, such as the thermoelectric...
