PURPOSE:To balance a load between power source equipments through simplified wiring without requiring adjusting work by calculating power consumption in each power source equipment digitally and transferring the data between the power source equipments. CONSTITUTION:At first, voltages at points (a), (b), (c), (d) in each secondary circuit are read out and stored in a RAM 42. Then a microcomputer 40 calculates power consumption in its power source equipment 400 and stores the calculated power consumption in the RAM 42. Then an average power consumption is calculated based on that data and data representing power consumption of load being transferred from other power source equipments 400, and the calculated average power consumption is stored in the RAM 42. Thereafter, the power consumption of load stored in its power source equipment 400 is compared with the average power consumption and next pulse ON times of power transistors 23a, 23b are controlled based on the comparison result and the current voltage levels at points (a), (b), (c), (d) stored in the RAM 24 thus averaging power supply from each power source equipment 400 to the load. |
