Power supply for motor control |
| abstract |
A power supply having a backup storage battery at the time of a power failure and operating a motor-driven load has a high power conversion efficiency that can maintain a battery capacity at the time of a power failure with high reliability and can cope with a prolonged power failure. Provide equipment. A power storage means connected to a fuel cell having a backflow prevention means in parallel with a storage battery is connected to a DC bus so as to be able to conduct electricity only in a direction from the fuel cell to the storage battery. In order to realize a device with high power conversion efficiency by reducing the power loss of the switching element, a bi-directional converter with a converter function that boosts the discharge from the storage battery side to the DC bus direction and steps down in the reverse charging direction It was interposed between the DC bus and the storage battery. The bi-directional converter includes a battery management unit that constantly monitors the storage battery, detects the storage battery capacity, and issues a refresh charge command, and a control circuit that automatically controls charging based on a signal output from the unit.
