Figure 7 shows the waveforms of a DC converter composed of one circuit. The reference current of each circuit is 25A, so the total charging current is 100A. Ib1, Ib2, Ib3 and Ib4 are the output currents of charging unit 1, unit 2, unit 3 and unit 4, respectively. IB is the charging current of the battery. Io1 is the output.
