    摘要: Disclosed is an active constant power supply apparatus, which rectifies power having various intensities and frequencies without using a high capacity condenser for a smoothing circuit which degrades the power factor of a circuit, and supplies constant power to a load. The active constant power supply apparatus includes an AC power supplier for supplying AC power; a rectifying circuit which receives AC power from the AC power supply unit and rectifies the received power; a driving coil connected in series to the load receiving power from the rectifying circuit; a power switch which switches the current passing through the driving coil and the load on/off; a pulse-type driving signal generator connected to a gate terminal of the power switch to control the switching on/off operation of the power switch; a turn-off decider which generates a turn-off signal when the current flowing along the driving coil has a value higher than the designed value, so as to turn off the power switch; and a pulse width controller which measures the control period ranging from the switch-on time of the driving signal generator to the switch-off time of the turn-off decider, and controls the driving pulse width of the driving signal generator such that the driving pulse width coincides with the control period.

    摘要: The present invention relates to the preparation of poly(amino oxalate) (PAOX) using oxalyl chloride, 1,4-cyclohexanedimethanol, and piperazinediethanol, the preparation of biodegradable polymer particles using the PAOX, and the use of PAOX particles as a drug delivery vehicle. The PAOX according to the present invention is a polymer that has three characteristics of biodegradability, biocompatibility, and cationic properties at the same time with appropriate hydrophobicity and thus can be prepared as particles that allow rapid drug release. Moreover, the particles improve the delivery efficiency of a drug into cells and thus can be efficiently used as a drug delivery vehicle for the treatment of acute inflammatory diseases such as acute liver failure and acute lung injury.
