Abstract: A power controller apparatus predicts demand power of a load apparatus, generated power of a power generator apparatus, and inherent stored energy of a battery apparatus. The power controller apparatus calculates excess electric energy and deficient electric energy achieved when the inherent stored energy reaches higher- and lower-limit stored energies, respectively. The power controller apparatus combines at least one first customer facility and at least one second customer facility having the excess electric energy and the deficient electric energy, respectively, and thus, forms at least one group including the first and second customer facilities. For each group, the power controller apparatus determines transmitting power from the first customer facility to the second customer facility, so that stored energy of each of the battery apparatuses of the first and second customer facilities is equal to or less than a first threshold, and equal to or more than a second threshold.

Abstract: A long-term predictor circuit predicts a long-term predicted power indicating temporal variations in consumed power of a customer, using a long-term prediction model indicating the variations for each moment of clock times. A short-term predictor circuit predicts a short-term predicted power using a short-term prediction model indicating the variations over a time interval before and after a change in a consumed power of each load apparatus, based on the variations over a time interval immediately before a current time, the short-term predicted power indicating the variations over a time interval immediately after the current time. A controller circuit controls charging and discharging of a battery apparatus by setting a charging power or a discharging power based on the long-term predicted power, and controls discharging of the battery apparatus by setting a discharging power based on the short-term predicted power.

Abstract: A voltage regulator includes chopper circuits connected in parallel, and a second series circuit. Each of the chopper circuits switches an input voltage and outputs the input voltage via a first inductor of a primary winding of a transformer, which includes the primary and secondary windings magnetically coupled with each other. The second series circuit includes a first series circuit and a third inductor connected in series, the first series circuit is configured by connecting second inductors of the secondary windings of the respective transformers of the chopper circuits in series, and both ends of the second series circuit are connected to first and second connection points connected to each other. The voltage regulator includes a first capacitor inserted between the first connection point and the output terminal, and a fourth inductor inserted between the first connection point and one end of one of the second inductors connected closest thereto.

Abstract: A switching power supply apparatus is provided with a switching circuit and an even number of transformers. The transformer are provided with: cores each having an identical shape; primary windings each having an identical arrangement around the cores, and each having first and second terminals; and secondary windings each having an identical arrangement around the cores, and each having third and fourth terminals. The primary windings of the transformers are connected so that when a current flows from the first terminal to the second terminal of a first transformer, a current flows from the second terminal to the first terminal of a second transformer. The secondary windings of the transformers are connected so that when a current flows from the third terminal to the fourth terminal of the first transformer, a current flows from the fourth terminal to the third terminal of the second transformer.
