In addition, the amplifying circuit M113 includes a pnp third transistor Q103 and an npn fourth transistor Q104 connected in multiple stages. This multi-stage connection is constituted by connecting the collector of the third transistor Q103 and the base of the fourth transistor Q104 to each other.

The operation and effects of the first filter unit M11 including the above configuration will be described. First, in the first filtering circuit M111, the first transistor Q103 is connected to the input power source The inductor L101 and the capacitors C102 and C103 connected to the collector of the first transistor Q101 are amplified in the same manner as in the first embodiment, The filter capacitor C101 removes the noise of the current flowing to the emitter side and re-inputs the noise to the first transistor Q101.

Thereafter, the input power from which noise has been removed via the first filtering circuit M111 is amplified while passing through the third and fourth transistors Q103 and Q104 of the amplifying circuit M113, The second transistor Q102 re-amplifies the inputted input power. At this time, the filter capacitor C101 of the second filtering circuit M112 performs noise rejection, The prevention diode D101 serves to prevent power backflow on the output side and the buffering inductor L102 provides buffering by storing input power transmitted to the rectifying part M12.

Next, the rectifying unit M12, which is a component of the power supply module M10, is configured to rectify the noise-canceled input power to generate a DC intermediate power source. The technique for AC-DC rectification is well known And a person skilled in the art will be able to carry out the present invention with sufficient reference to the prior art, and a detailed description or illustration of the rectifying section M12 will be omitted.

The second filter unit M13, which is a component of the power supply module M10, includes a first power supply circuit M131 for supplying the intermediate power supply to the converting unit M14 when the power supply is turned on, A second power supply circuit M132 for supplying intermediate power to the converting unit M14 and a noise of an intermediate power connected to the output terminals of the first and second power supply circuits M131, And a third filtering circuit M133 for canceling the third filtering circuit.

When supplying power to the server M via the power conversion unit M14, the first power supply circuit M131, The second power supply circuit M132 is operated when the power supply is off, that is, when the power supply is not supplied to the server M via the converter M14 And transfers the intermediate power to the converter M14.

In particular, the second filter unit M13 has a meaning at the moment when the power is turned on / off. More specifically, when the power is turned on, the third filter unit M13 is turned on until the storage capacitor C105 is fully charged. The bias rectifier diode R101 and the bias rectifier diode R101 and the bias resistor R111 and the bias resistor R101 are connected to each other by the storage capacitor C105 of the first power supply circuit M131 at this time, Since the bias voltage distributed by the capacitor C107 is higher than the emitter voltage of the first switching transistor Q105, the first switching transistor Q105 maintains the cut-off state and the second switching transistor Q106 operates, The third filtering circuit M133 forwards the power to the third filtering circuit M133, and the third filtering circuit M133 destroys the inputted or generated noise through the emitter side ground of the filtering transistor Q107 and supplies it to the converting unit M14 .

The second switching transistor Q106 is turned off and the storage capacitor C105 is turned off because the second switching circuit M132 can not be driven by the voltage charged in the storage capacitor C105 when the power is turned off, The first switching circuit M131 is driven to transfer the intermediate power supply to the third filtering circuit M133 and the third filtering circuit M133 supplies the input or generated noise to the emitter side ground of the filtering transistor Q107, And supplies it to the converting unit M14.

The control circuit M144 controls the output terminal of the inverting comparator COM1, the output terminal of the OR gate OR1, And a modulation control element MC connected to the circuit M141.

The operation and effect of the converter M14 including the above configuration will be described. Generally, a periodic signal (clock, CLK) is required for the operation of the server M, , And a pulsed power supply (power supply). In order to supply such a pulsed power supply, PWM control is utilized. When a power supply (hereinafter referred to as a long period power supply) for lengthening the clock period is supplied, the PWM control becomes inefficient. In order to solve this problem, the converter M14 has an effect of improving the power supply efficiency by switching to the PFM control when supplying power for a long period.

To this end, the converting unit M14 compares the reference voltage and the voltage and phase of the supplied power source stored in the storage circuit M142 with the comparing circuit M143. When the phase of the supplied power source is equal to the reference voltage, the control circuit M144 PWM control is performed, and when there is a phase difference (power supply for a long cycle), the control circuit M144 performs PFM control to maximize efficiency.

6, the state detection module M30 includes a state detection section M31 for detecting a data processing state of the server M, that is, a clock cycle, and a temperature detection section M32 for detecting a temperature rise of the server M ).

More specifically, the state detector M31 includes a monitoring element M311 for sensing a clock cycle used in the server M, and the temperature detector includes a temperature sensor M321 for sensing the operating temperature of the server M .

Through the configuration of the state detection module M30, the control module M20 continuously detects the state of the server M and controls the power supplied to the server M according to the operation state of the server M. [ For example, when the clock period of the server M needs to be reduced, the state detecting unit M31 detects the clock period of the server M, and based on the clock period, the control module M20 supplies the power- So as to reduce the pulse period of the power supply. As another example, when the temperature of the server M abnormally rises due to an abnormality in the server M, the temperature detector M32 detects the operating temperature of the server M, And controls the supply power supplied from the power supply module M10 to be urgently cut off.

In particular, the control module M20 is preferably supplied with power at all times in preparation for an emergency. For this purpose, the drive control means controls the control module M20 even in an emergency such as sudden power- ) Can be operated normally so that it can cope with the accident appropriately.

More specifically, the emergency power module M40 is connected to the output terminal of the second filter M13 and receives and stores the intermediate power from the second filter M13.
