Description
Technical field
The present invention relates to field of power supplies, specifically be meant and reduce power supply at standby or a kind of energy-saving circuit of input power consumption when non-loaded.
Background technology
Various electric equipment productss have been indispensable parts during people live, and the extensive application of electric equipment products has brought huge energy resource consumption.Show that according to the China energy office data 2009, Chinese whole society power consumption reached 36,430 hundred million kilowatt hours, increases by 5.96% on a year-on-year basis, increasing degree improves 0.47 percentage point than the previous year.The electrical network power consumption is increasing substantially, and energy supply reduces day by day, in order to tackle this global problem, comprises that the national governments and the mechanism of China issued and energy-saving and emission-reduction relevant policy and rules in succession.Like the external power source efficiency rules V4 of U.S. efficiency standard EPS V2.0, Chinese efficiency standard GB 20943-2007, European Union and ERP instruction, the MEPS in Australia, MKE of Korea S etc.; Do not meet the power supply of these standard-requireds, can not get into these countries and sell.The requirement of these standards is mainly reflected in two aspects: the one, and stand-by power consumption; The 2nd, average efficiency.The stand-by power consumption of power supply is the loss of fixing, and reduces stand-by power consumption and can reduce the waste in vain of electric energy quilt, helps energy-saving and environmental protection.
Stand-by power consumption is the constant power loss when being in holding state of not working of the function of tonic chord part of electric equipment.For example, after we use a teleswitch closing television, also be the remote-control receiving circuit power supply because the inner standby power of television set still is in on-state with electrical network, so television set is still expending electric energy under standby or sleep pattern.Although the power that standby power, remote-control receiving circuit consume is very little, owing to adopt inefficient power supply (like linear power supply), can't reduce the power consumption under the holding state, the result tends to waste several watts power.
No-load power consumption is meant equipment employed electric energy when breaking off with load and not carrying out any function.For example, patch the power supply adaptor, charger of the portable set on wall socket etc.,, but still can consume the power of 0.1W to 1W though do not link to each other with equipment, have in addition consume more than the 2-3W.Though it is insignificant that the idling consumption of individual equipment possibly seem, the standby consumed power of every household electrical appliances of all families adds up, and is very surprising numerical value.Estimate that according to International Energy Agency the household electrical appliance consumption of global 5-15% all produces under standby mode.Along with the increase of popularizing and having the new equipment of Electronic Control and multiple function of household electrical appliance, this problem also will become increasingly conspicuous.
Can be divided into high frequency switch power and power frequency linear power supply by the working method power supply, this power supply of two types has developed and had produced many years, in social economy and people's life, has brought into play important function; But; These adopt the power supply of conventional art, and stand-by power consumption is higher relatively, and this type number of power sources in moving and using at present is hundreds of millions of; Therefore, wasted a large amount of electric energy.Along with national governments and mechanism have issued and energy-saving and emission-reduction relevant policy and rules in succession, power supply manufacturer has designed and has produced standby power less than 0.3W even be lower than the Switching Power Supply product that 30mW can satisfy standard, but generally is used to mate new electric equipment products; These high energy consumption power supply purposes are very extensive; Enormous amount wants to replace fully at short notice, and expensive is sizable; The wasting of resources is also huge, and is very unrealistic; And, in some field, because of the noise of Switching Power Supply more much bigger than linear power supply, to some specific function can cause disturb and work undesired.
In sum; For waste and the Capital expenditure that reduces resource; Also to satisfy society simultaneously to the requirement of energy savings, be necessary to invent out and a kind ofly do not destroying existing electric equipment power supply architecture and be issued to the energy-saving circuit device of above-mentioned purpose with the prerequisite of the annexation of power supply and electrical network.
