摘要： The disk array device supplies appropriate power to various parts in accordance with the operating mode in cases where the output of the main power supply drops. The disk array device adjusts the power from a commercial power source 6 with an AC/DC power supply 5, and supplies this power to a power supply common bus 7. A disk drive group 1 and a control circuit board group 2 constituting electrical loads are respectively connected to the power supply common bus 7. When the supply of power from the main power supply stops, the capacitor box 3 supplies a relatively large current for a short time only, in order to retain data during an instantaneous power outage. Then, the battery boxes 4 supply power to the power supply common bus 7 for a relatively long period of time, in order to perform destage control and memory backup. The battery boxes 4 perform balancing control of the output current in order to suppress variation in the output current value among the battery boxes 4.

摘要： A step down type DC-DC power-supply device implements both the stabilization of the control loop and the responsibility at the same time. In the power-supply device, an output power signal is fed back to an error amplifier after having passed through a CR smoothing filter provided independently of a power LC smoothing filter. Also, independently of the duty controls over Power MOSFETs, i.e., upper-side/lower-side semiconductor switching components in the steady state, an output from the power LC smoothing filter is added to an upper and lower limit-mode-equipped control circuit, thereby, at the transient state, forcefully setting the duty α at either 0% or 100%.

摘要： The invention relates to a power supply system having plural converters connected in parallel. The current of each of the plural converters is detected and each of the converters is controlled so as to match each of the converters to a maximum current value from among the detected current values. In the parallel converters, when one or more converter fails, having an output current of zero, the remaining converters are each partially charged equally to maintain the load current. Since a common bus is arranged between plural converters and plural loads, it is possible to carry out a redundant operation having a high reliability. Since a stable output can be obtained without being affected by the failed converter, a power supply system having the redundancy and the high reliability can be attained.

摘要翻译： 本发明涉及具有并联连接的多个转换器的电源系统。 检测多个转换器中的每一个的电流，并且将每个转换器进行控制，以使每个转换器与检测到的当前值中的最大电流值相匹配。 在并行转换器中，当一个或多个转换器出现故障时，输出电流为零，剩余的转换器各自部分充电以保持负载电流。 由于在多个转换器和多个负载之间设置公共总线，所以可以执行具有高可靠性的冗余操作。 由于可以在不受故障转换器影响的情况下获得稳定的输出，因此可以实现具有冗余性和高可靠性的电源系统。
