A power conversion apparatus including a power converter, a first output port, a second output port, a load detection circuit and an output selection circuit is provided. The power converter generates a first and a second output voltages having different voltage specification. The first and the second output ports respectively provide the received output voltages to a back end. The load detection circuit is coupled with the power converter and the second output port and detects a load requirement of a load connected to the second output port to generate a load detection signal. The power converter generates a first switch control signal according to the load detection signal to control the output selection circuit, such that the output selection circuit provides one of the first and the second output voltages in response to the first switch control signal.

The present invention relates to a bimetallic mercaptan conversion catalyst for sweetening liquefied petroleum gas at a low temperature, which is prepared by using an Al_(2)O_(3)-SiO_(2) composite oxide as a carrier to support bimetallic active components vanadium and nickel. The bimetallic mercaptan conversion catalyst has a proper specific surface area and more metal active center sites, and has advantages of simple preparation, efficient mercaptan conversion even at a low temperature, and no saturation and polymerization of olefins. The bimetallic mercaptan conversion catalyst exhibits superior mercaptan conversion performance in LPG sweetening, has strong adaptability to starting materials, and can also nearly completely remove trace of carbonyl sulfide contained in LPG.

The invention is directed to a low-dropout voltage regulator (LDO), including a power transistor, a driving stage circuit, a feedback circuit, a bias power source and an auxiliary reference current generation circuit. The power transistor is controlled by a driving signal to convert an input voltage into an output voltage. The feedback circuit generates a feedback voltage according to the output voltage. The driving stage circuit generates the driving signal according to the feedback voltage and the reference voltage. The bias power source provides a bias current. The auxiliary reference current generation circuit is configured to sample an output current, adjust the sampled output current to generate an adjustment current by means of mapping and superpose the adjustment current onto the bias current to generate a reference current to control drive capability of the driving stage circuit.
