The cross reference of related application
The application requires the name of submitting on Dec 11st, 2012 to be called the rights and interests of the korean patent application No.10-2012-0143678 of " Power Supply Apparatus and Control Method Thereof ", is incorporated into by reference in the application in these its all the elements.
Technical field
The present invention relates to supply unit and control method thereof.
Background technology
Conventionally, because of be the switching type power supply that configured by supercharging converter (boost up converter) etc. (hereinafter, be called as SMPS) be condenser input type, wherein carry out rectifying and wave-filtering (rectification smoothing) at input side, when power input is applied in now, charging current flows in the capacitor of current rectifying and wave filtering circuit.
Electric current is called as the electric current of surging, and when the voltage of power input for maximum and its phase place be 90 to there is maximal value while spending.
In this case, in order to protect the on/off switch contact of power input and to prevent the interference of power circuit, need to control surge current.
Related to this, according to prior art, utilize the relay and the resistor that are connected in parallel to each other to limit the surge current of introducing from battery supply.
As example, be configured to comprise that according to the switching type power supply of above-mentioned prior art alternating current (AC) power supply, relay, commutation diode, surge current prevent circuit and capacitor.
Now, AC power supplies is the commercial AC power supply providing by power supply entry terminal.The supply of relay switch AC power supplies, and the AC power supplies of commutation diode full-wave rectification input.
Surge current prevents that circuit from comprising resistor and relay.Relay changes according to its ON/OFF state the path that electric current flows through.Resistor prevents from applying the commitment overcurrent flows of power supply.
Capacitor stored charge is to become voltage filter (smooth) DC current (DC) voltage and to provide DC voltage to back loading (rear load).
In prior art as above, after power switch is switched on, relay is in on-state, so so that AC electric power by commutation diode and resistor, then in capacitor, be changed.Conventionally,, because capacitor has very large electric capacity, surge current flows at the commitment that electric power is provided.
In this case, the size that resistor has reduced inflow current flows to prevent surge current.
In addition,, after past predetermined time, surge current prevents that the relay of circuit is switched on by control module.Therefore, the electric current that is applied to capacitor by resistor flows through relay, and so its size increases.
But, need to there be very large electric capacity and many-contact relay in power supply entry terminal side according to the anti-locking apparatus of the surge current of prior art described above.The above-mentioned relay of mentioning has increased cost and the volume of product.
Meanwhile, as another prior art, there is the scheme of utilizing NTC.In this scheme, the stage can have large impedance with limit inrush currents to NTC in early days.Then,, under normal condition, because electric current causes the generation of heat, NTC resistance is reduced.
In another prior art as above, the current drain of equipment has increased in this case, and cost has improved.
In other words, all NTC should allow the rated current that is suitable for electric current under normal condition to flow.Therefore, should use and have jumbo NTC, this causes the increase of cost.
