Abstract: 본 발명의 스텝 다운 컨버터는 a) 스위치의 턴온에 따라 전원용 인덕터를 자화시킨 후 전원용 캐패시터의 전압이 소정값으로 클램핑되기까지 전원용 인덕터와 전원용 캐패시터의 공진을 수행하고 스위치가 턴오프되면 출력 임피던스에 따라 방전 속도가 달라지는 전원용 캐패시터의 방전을 통하여 부하단에 정전류가 흐르도록 하는 전원부 및 b) 스위치의 턴온에 따라 전원부의 출력에 따라 출력용 인덕터와 출력용 캐패시터에 에너지를 축적한 후 스위치의 턴오프 따라 축적된 에너지를 공급함으로써 부하단에 정전류를 공급하는 출력부를 포함한다. 본 발명은 병렬 동작시 전류 불균형을 제거할 수 있고 입출력 관계의 선형성을 향상시킬 수 있다.

Abstract: PURPOSE: A test debugging method using an AHB(Advanced microcontroller bus architecture High-performance Bus)-UART(Universal Asynchronous Receiver/Transmitter) and a system thereof are provided to verify metering data by generating the metering data with a reliable method. CONSTITUTION: A reliability driving module executes metering software installed in a cloud computing system. A TPM(Trusted Platform Module) provides a security function for metering data generated by the metering software in a cloud computing service. The reliability driving module includes a TXT(Trusted Execution Technology) unit. When a hash value of a program operated by a program list exists on a program list, the TXT unit executes the program.

Abstract: PURPOSE: A data input/output facsimile device is provided to verify a circuit related to an input/output of a computer processor and an input/output operation although an actual hardware corresponded to the input/output does not exist. CONSTITUTION: A PCI(Peripheral Component Interconnect) interface(1) is provided for connecting to a computer having a facsimile device. An EEPROM(Electronically Erasable Programmable Read-Only Memory)(2) limits an input/output address adapted to a computer processor(8). A look-up memory(3) stores each channel data with respect to an analogue and serial input/output of the computer processor(8). An EPLD(Electrically Programmable Logic Device)(5) controls operations of a FIFO(4), the look-up memory(3), and a dual-port memory(6), and connects the PCI interface(1). A FIFO(First-in First-out)(4) stores a used signal status whenever a read/write control signal with respect to an input/output is generated. The dual-port memory(6) stores data with respect to an input/output of a digital pattern. A MUX interface(7) is provided for connecting to the computer processor(8) necessary for a facsimile with respect to the input/output.
