Abstract: PURPOSE: A switching buck converter reduces noise, increases efficiency, minimizes loss, and increases power intensity of the converter by improving a switching way of a main switch into a soft switching way for zero-voltage switching. CONSTITUTION: A switching buck converter includes a leakage inductor (Lr); a coupling inductor (Lb) connected to the leakage inductor and minimizing an increase in the current of the leakage current; a main switch (Sb) connected to the coupling inductor in series and applying a difference between an input voltage and an output voltage in an on state to the coupling inductor; a main diode (Db) turned on to make the current of the leakage inductor 0 when the main switch is turned off; an auxiliary switch (Sx) reducing the input voltage of the main switch; and an auxiliary diode (Dx) applying the negative output voltage to the coupling inductor.

Abstract: PURPOSE: A device and method for providing high image data compression for satellite are provided to highly compress an image signal of a large amount obtained form an image mounted body of a satellite in real time. CONSTITUTION: An observation image data is received form an image information obtaining unit of an satellite(S2100). Non-video data and classification data is removed from an observation image data(S2200). A discrete wavelet transform is proceeded by dividing an observed image data which compressed preprocessing is performed into a tile of predetermined size. Data which is encoded by a CTX and a D is encoded with MQ.
