Sleep control circuit and modular power based on sleep control circuit

Abstract

The invention discloses a sleep control circuit and a modular power based on the sleep control circuit. The control circuit includes three illumination sources and three photoreceivers, wherein a first end of the first illumination source is connected with a second end of the second photoreceiver, a second end is connected with a first end of the second photoreceiver, the second end is a control end of the power, a first end of the second illumination source is an enablement control end for receiving an enablement signal, a second end is connected with a first end of the third photoreceiver, the first end of the second photoreceiver is connected with a first end of the third illumination source, the second end is a sleep control end, the second end is an enablement detection end, the firstend of the third photoreceiver, the second end of the third illumination source and the first end of the first photoreceiver are electrically connected with the power ground, the current conduction direction of each illumination source is respectively from the first end to the second end, when the illumination source is turned on, the first end to the second end of the corresponding photoreceiverare turned on. The control circuit is advantaged in that standby loss of the modular power is reduced to an extremely low level, huge economic benefit is generated, and great energy saving and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the field of modular power supplies, and relates to a dormancy control circuit and a modular power supply based thereon. Background technique [0002] At this stage, more and more functional components begin to appear in equipment or systems with a modular structure, for example, power supplies appear in equipment or systems with a modular power supply structure. The modular power supply can combine multiple power modules according to requirements, so as to control the maximum power operating point of the power curve and achieve high power output in a wide power range. Modular power supply network has gradually become the mainstream of power supply due to its outstanding advantages such as convenience and easy maintenance. [0003] At present, when the load of the modular power networking system is less than the capacity of multiple power modules, the existing control method is to turn the redundant power modules into a standb...

Problems solved by technology

[0004] However, when the power module is turned into standby, some circuits still maintain work and need to consume a certain amount of power. Since each power module in the network has its own minimum power consumption required for standby and sleep, each power module is in standby and sleep. The superposition of the required minimum loss will cause the problem of excessive standby and sleep loss of the entire system. The above problems exist in the modular communication power supply, charging pile module, modular UPS, and modular energy storage system.
