Problems solved by technology

Although such a design is the most convenient method, it also causes the power conversion device to operate from a low load capacity to a high load capacity, because the power conversion modules used to provide power are different but the ground terminals are connected together, and the standby When the power conversion module is under no load or very light load, it is susceptible to the influence of the main power conversion module from low load to high load, resulting in abnormal shutdown

Embodiment Construction

[0035] Please refer to figure 1 , which shows a circuit block diagram of the power conversion device according to the present invention. The power conversion device 10 receives an input power Vin, and provides power for the electronic device 20 connected to its output terminal under different operating states. The electronic device 20 can be, for example, a personal computer or a server. The power conversion device 10 can operate in the standby mode or the non-standby mode according to the difference of the pumping power of the electronic device 20 . Generally speaking, when the electronic device 20 enters no-load operation, the power conversion device 10 enters the standby mode to reduce power consumption and improve overall efficiency; when the electronic device 20 enters medium-load or heavy-load operation, the power conversion device 10 is out of standby mode. mode and enter the non-standby mode to increase the power supply capacity to cope with the load of the electroni...

Abstract

The invention discloses a power conversion device and a method for preventing abnormal shutdown of the power conversion device, wherein the method for preventing abnormal shutdown of the power conversion device comprises the following steps: providing a power conversion device, including a main power supply module and a standby power supply module, the standby power supply module It is electrically connected to the main power supply module and provides the operating voltage required by the multiple microcontrollers of the main power supply module; when the power conversion device enters the non-standby mode and the standby power converter of the standby power supply module stops working, the operating voltage monitoring program is executed to monitor the operating voltage; and before the operating voltage is lower than the minimum compensation voltage, the standby power converter is forcibly activated to avoid abnormal shutdown of the power conversion device.

Description

technical field [0001] The present invention relates to a power control method, and in particular to a method for preventing a power conversion device from shutting down abnormally due to low operating power when it leaves the standby mode. Background technique [0002] A power conversion device is generally a basic power supply unit used to deliver power to meet the needs of electronic devices. In order to increase the output power of the power conversion device to meet the load capacity of the electronic device when the load capacity of the electronic device is high, and reduce the output power of the power conversion device to save energy when the load capacity of the electronic device is low. The power conversion device can be designed to have two groups of power conversion modules, one group of power conversion modules (hereinafter referred to as the main power conversion module) is used to provide power for electronic devices operating under high load capacity, and the...
