The relay drive circuit can be widely applied to a plurality of household electrical appliance products, office supplies and other electric appliance products.
Description
Technical field
The utility model has related to a kind of relay drive circuit.
Background technology
Stand-by power consumption refers to connect to be gone up mains supply and connects all power consumption equipments but do not start, and this moment, overall power dissipation was mainly from the no-load loss of power supply self and the stand-by power consumption of equipment.The real power consumption of power supply generally can be about 5W～10W in this state.
The electric energy that electric equipment products are consumed when standby has become a kind of severe energy waste.Find that according to the investigation of Chinese CECP have the household electrical appliance of idle function that kind surplus in the of 10 is nearly arranged in the urban family, every monthly average stand-by power consumption is between 15-30 watt, this numeral accounts for about 10% of family's power consumption.That is to say that the electricity charge the inside of payment every month has one one-tenth to be to check for standby, so the potentiality that power-saving technology is deep-cut in addition.
On December 18th, 2008, European Commission has announced " committee's regulations (EC) No 1275/2008, with regard to family expenses and the ecological designing requirement of office with electronic electric equipment standby and shutdown mode power consumption, carry out the instruction 2005/32/EC of European Parliament and council ", this first implementing measure that indicates the EuP of European Union instruction is formally put into effect.These regulations have been done specific requirement to family expenses and office with the ecology design of electronic electric equipment standby and shutdown mode power consumption.Regulations require to implement in two stages its power consumption limit value:
Phase I: after regulations come into force 1 year, power consumption must not surpass 1 watt under shutdown or the standby mode that activates again, had the standby mode power consumption that information or state show and must not surpass 2W;
Second stage: after regulations come into force 4 years, shutdown or activate again that power consumption must not surpass 0.5W under the moving standby mode, and the standby mode power consumption with information or state demonstration must not surpass 1W.
European Union is about to the second stage of the regulations of entering, therefore more and more higher to the requirement of standby and shutdown mode power consumption to the family expenses and the office of outlet European Union with electronic electric equipment, the standby effect of the at present domestic household electrical appliances and the electrical equipment of handling official business does not generally reach the following requirement of 0.5W, therefore requires domestic product man to be badly in need of designing a kind of circuit that can satisfy the EuP requirement yet.
The utility model content
The technical problems to be solved in the utility model is in order to solve technical barrier recited above, a kind of relay drive circuit of standby effect below 0.5W to be provided
In order to solve technical problem recited above, the utility model is taked following technical scheme:
A kind of relay drive circuit is provided, includes the pressure unit, rectification unit, filter unit, relay drive unit and the power supply output unit that electrically connect successively.
Described pressure unit includes series resistance R1, R2, the capacitor C 1 that is arranged in parallel with series resistance R1, R2.
Described rectification unit includes the half-wave rectifier of being made up of diode D1, D2.Half-wave rectifier utilizes the unidirectional on state characteristic of diode, is being input as under the situation of standard sine wave, and output obtains sinusoidal wave just half part, and negative half part then loses.
