Problems solved by technology
[0004] At present, there are some methods to solve the above problems: one is to connect an electronic switch or relay in series in each group of output circuits to switch between standby and work. This method will lead to a straight-up cost increase for equipment with multiple outputs and high current and low voltage, and will reduce the conversion efficiency of the power supply, resulting in a waste of energy.
The second is to add a low-power auxiliary power supply compared to the traditional standby technology. The auxiliary power supply provides the working voltage for the standby control circuit and turns off the main power supply to achieve standby.

The invention discloses a novel power supply standby circuit which is characterized in that the power supply per se is turned into a working state and a standby state through a control signal, furthermore, any other auxiliary power supply is not required, the novel power supply standby circuit is different from the traditional power supply standby mode, and the output voltage of the power supply is composed of a standby power supply voltage and a main power supply voltage; the main power supply voltage is switched off when the power supply receives a standby signal, the power consumption is reduced, the standby power supply voltage is not changed; working voltage is continuously provided for the standby control circuit, the switching off of the main power supply voltage is not the true switching off, but a method for reducing the output voltage to realize standby according to a certain ratio, and the larger the ratio of reducing voltage is, the lower the standby power consumption is; and the power supply response is quick and reliable by the standby technology, the standby power consumption is extremely low, the cost is low, and the standby technology is easy to graft and popularize.
Description
technical field [0001] The invention relates to all fields of high-frequency switching power supplies, especially the standby technology of high-frequency switching power supplies used in household consumer electronics products. Background technique [0002] With the continuous improvement of human living standards, various electrical appliances and equipment, and special household appliances are becoming more and more popular in every ordinary people's home. While the rapid development of electronic technology continues to bring comfort and convenience to our lives, it also brings huge energy waste, and the world's energy is increasingly tense. Throughout the world, the international market has strict restrictions on the energy consumption indicators of various electrical equipment. High-efficiency, energy-saving, green and environmentally friendly electronic products are the development trend. To develop high-efficiency, energy-saving, green and environmentally friendly ...
