POWER SUPPLY DEVICE, AND METHOD OF CONTROLLING POWER SUPPLY DEVICE |
摘要 |
A storage (80) stores a first drooping characteristic of a rated current Ioc1, and a second drooping characteristic of an allowable current value Ico2 that is greater than the rated current value Ioc1. A controller (70) is configured to select a drooping characteristic stored in the storage (80) in accordance with the current value detected by an output current detector (50) and a mask condition, and perform droop control. |

1. A power supply device comprising:
a storage storing a first drooping characteristic of a rated output current value, and a second drooping characteristic of an allowable current value that is greater than the rated output current value; an output current detector configured to detect a load current value; a controller configured to select a drooping characteristic stored in the storage in accordance with the load current value detected by the output current detector and a mask condition; and a transformer including a first coil and a second coil and configured to perform conversion of a voltage, wherein the first coil is connected to a switching element, the second coil is connected to a rectifier element and an output choke coil, the output choke coil has a magnetic bias gap, the rated output current value is a rated output current value of the output choke coil, and the allowable current value is a current value enlarged from the rated output current value by the magnetic bias gap. |
