Abstract: AC motor driving system and driving method thereof are provided. The driving system and method are capable of increasing power factor, adjusting waveform of the DC ripple voltage for increasing driving efficiency. The driving system is basically constructed by connecting three circuits. The first circuit is a three-phase full wave rectifying circuit and is used to transfer commercial electricity to a first DC voltage. Then, the second circuit is used to transfer the first DC voltage to a second DC voltage that ripples voltage thereof having a semi-sinusoidal waveform. The third circuit is an AC driving circuit, and receives the second AC voltage for driving the AC motor. Thereby, the driving efficiency can be increased. The capacitance used in the present disclosure has low capacitance value, thus the power factor can be increased, and usage time of the AC motor driving apparatus can also be increased.

Abstract: A light-emitting diode driver includes a power switch, a logic unit and a pulse adjustment signal generator. The power switch is used to control a charging level of a light-emitting diode voltage terminal, and controlled to be turned on or off by a pulse-width modulation signal. The logic unit is coupled to a control terminal of the power switch, and used to generate a frequency control signal. The pulse adjustment signal generator is coupled to the logic unit, and used to generate an operational wave according to the frequency control signal and update the pulse-width modulation signal according to the operational wave. When the duty cycle of the pulse-width modulation signal is smaller than a pulse-width modulation threshold, the operational wave has a first frequency. When the duty cycle of the pulse-width modulation signal is larger than the pulse-width modulation threshold, the operational wave has a second frequency higher than the first frequency.

Abstract: A semiconductor package is proposed, in which a substrate is formed with a chip bonding area and a plurality of bond fingers surrounding the chip bonding area, and a plurality of bridging elements are disposed in a stagger manner between the chip bonding area and the bond fingers on the substrate. Multiple wire bonding processes are performed to bond first gold wires between the chip and the bridging elements, and bond second gold wires between the bridging elements and the bond fingers. This therefore significantly shortens a wire bonding distance as compared with only one time of wire bonding for electrically connecting the chip to the substrate. As a result, wire bond operability is improved, and the shortened wire bonding distance reduces wire length so as to enhance resistance of the gold wires to mold flow impact during molding, thereby preventing wire sweeping or wire sagging from occurrence.
