Problems solved by technology

However, once the AC power is connected, existing power conversion devices will still provide DC power normally if the electronic device is not connected or the connected electronic device is turned off
Therefore, the current power conversion device cannot adjust the output power according to the state of the connected electronic device, resulting in a lot of unnecessary power consumption

Embodiment Construction

[0050] In order to prevent the power supply system from unnecessary power consumption, an embodiment of the present invention provides a power conversion device. An external signal is transmitted between the power conversion device and the electronic device. According to this, the power conversion device can learn the power demand of the connected electronic device from the external signal, and then dynamically turn it on or off, so that the power conversion device can provide suitable power. The required power supply can achieve the effect of saving electricity.

[0051] The technical content, features and effects of the embodiments of the present invention are described in detail below with reference to the drawings. Furthermore, wherever possible, elements / members using the same reference numerals in the drawings and embodiments represent the same or similar parts.

[0052] figure 1 It is a block diagram illustrating a power supply system 100 according to an embodiment of...

Abstract

A power conversion apparatus is provided. The power conversion apparatus includes an AC to DC adapter, an input port, a power conversion control unit, and a restart circuit. The AC to DC adapter converts an AC input voltage into a DC output voltage according to an external signal of an electronic apparatus and provides the DC output voltage to the electronic apparatus. The input port receives the AC input voltage through an AC input terminal. If the power conversion apparatus does not output the DC output voltage to the electronic apparatus, the power conversion control unit turns off the power conversion apparatus. If the restart circuit detects that an insertion action occurs on the input port, the restart circuit transmits a trigger signal to turn on the power conversion control unit in an off mode.

Description

technical field [0001] The present invention relates to a power control technology, and in particular to a power conversion device with power saving function. Background technique [0002] Today's consumer electronic devices (such as desktop computers, notebook computers, mobile phones, digital cameras, and tablet computers) use built-in batteries or use external power conversion due to the desire to save their weight. to receive power. In other words, these electronic devices need a power conversion device, such as an AC to DC converter (AC to DC adapter), to provide their power or to charge their built-in batteries. [0003] For the existing power supply system, the power conversion device is a passive device. That is to say, when the input terminal of the power conversion device is connected to the AC power, the power conversion device passively provides stable DC power to the electronic device connected thereto. However, once the AC power is connected, the existing po...
