Description

IX. Description of the invention: [Technical field to which the invention pertains] In particular, it is applied to a power supply device in a power supply system having a system switching circuit that switches the circuit to select and output a standing power source. [Prior Art] Nowadays, when the computer motherboard is changed from the AT specification to the Ατχ specification, the controller also changes its architecture. The most special one is that the power supply is output and output.

Electricity and - standing power are respectively provided by the power supply - the main power; two: the power system provides, wherein the standing power system is: ϊ ϊ 为 for the standing power 'and the normal state provides the standing power formation, sleep mode If the scale can reach the remote starter Wei required by the ΑΤΧ specification, when the user presses the power button or commands the power reserve by remote remote control mode, the standby power makes the main power 2 ΓΓ And the main power system generates the main output power supply electronic device, as shown in FIG. 1 'the conventional power supply has the wave rectifying unit 丨, the power factor correction

ΓΙ, a main power system 3, and a standing power system 4, when the filter rectification unit 1 takes the input-input power 9丨, then passes the wave, rectifies, and adjusts the phase through the power factor correction unit 2, however, the main power The system 3 further includes a main pulse wave control unit 31 and a main power conversion single magic 2, when the recording (four) unit 31 is not obtained, the problem power system cannot work, ie, the main power system 3 cannot output power normally; The standing power system* package: a standing pulse wave control unit 41 and a standing power conversion unit, the standing pulse wave control unit 70 41 obtains a reference frequency signal 95, and obtains the input power % according to the reference The frequency-driven the conventional power conversion unit 42 converts and generates a normal power % output to an output terminal 97 'β constant power edge 4 and generates a -first standby signal to the power management unit 5, and waits - the remote opening and closing is reduced 94 After the Wei Li management unit 5, the Wei Li management unit 5 transmits the sinusoidal bias power to start the sinusoidal main pulse control unit 31, so that the main power system 3 starts to work, and provides - the main input iijf force 92 to the other - output 97; When the main power system 3 is activated, the main power line 3 and the pulse wave control used by the standing power system 4 and the transformer circuit for converting the power are independent devices. Therefore, the main power record 3 of the power supply and the standing power system $ both generate losses, which will cause the negative impact of 5 1361539 input/output conversion efficiency and excessive waste heat, and the above two negative effects will indirectly increase the design. The cost and damage to the life of the source H supply, but the above-mentioned standing power system 4 is still used to the power supply (4), the previous technical flight is not the same, the system 3 and the s Xuanchang standby power system 4 simultaneously The lack of loss has to be changed. [Invention] Since the conventional power system of the power supply in the prior art still works after the main power money works normally, causing additional loss, the object of the present invention is to provide a circuit year to configure the power supply. The standing power system can be operated after the main power system starts to output: reduce losses.

The invention provides a power supply device with a system switching circuit, the power supply device comprises a main power m backup power system and a power management unit, and the power management unit obtains - the standby power is activated after receiving - the remote opening and closing The signal is triggered, which in turn generates - the power of the main power to start the work, and the system switching circuit is triggered by the remote opening and closing signal ^ ^ the standing power Wei obtains the input power or the power path of the reference city In order to suspend the power supply of the power supply, the power supply circuit of the power source can be used to generate the power source to generate the standby power. Can _ the standing power Weiqi low secret effect, and after the ^ restart the standby power system to resume standby state, turn the power supply to pay * operation, and reduce the loss effect. [Embodiment] For the detailed outline and technical know-how of this (4), the current brain is as follows: See Figure 2, the m system switching circuit of the present invention is applied to have the main power system 3, - standing power secret 4 And a power supply unit of the power management unit 5, the main power system 3 includes a main pulse wave unit 31 and a main power port unit 32, the standing power pulse wave control unit 41 and the standing power conversion unit 42, The power supply is for the j'H-input power 91, and the standing pulse control unit 41 of the standing power system 4 takes the test frequency signal 95' and drives the standing power to convert the input power W according to the reference frequency thereof.诅 # #/4t咖丄 for the early 42 turns for the supply * "increase and decrease - hoisting power 93 supply to - output 97, while the conversion is early 7 〇 42 generated - the first _ standby age of the power management unit 5 start At this time, 丄361539, the power supply wire is ready to be out of the state; when the power supply unit H 4 starts the power management unit 5, the power can be output by the remote end, and the output is biased. Intermittent power to power the early force _ for - the main output == 冤 冤 92 92 supply to another loss End 97, :, after the power is again received by the remote opening and closing signal 94 "force" to close the main power system 3; the power supply is more set = partial 3 electric ^ circuit replacement money _ end off % Pain out the standing, '= signal % power path to stop the standing ^

The power system or the reference frequency signal 95 obtains the input system switching circuit including the bypass unit 6 power 93; wherein the rate signal 95 is obtained by the input power 91 or the reference frequency or the phase rate is closed. The signal 94 is triggered, and the input power 91 has output a 5 Hz first standby signal to activate the power management unit 5, and the remote control signal 94 is triggered to trigger the power management unit to be driven by the power.
