    • A resonant converter for improving synchronous rectification control is provided. The resonant converter obtains an input power, and through a switch unit, the period of the input power to be transmitted to a resonant circuit can be modified. The resonant converter further includes two transformers electrically connected to the resonant circuit, two synchronous controllers electrically connected to the primary sides of two transformers respectively, and two synchronous rectifiers electrically connected to the secondary sides of two transformers. The input power modified by the resonant circuit is obtained by the primary sides of two transformers, and two induced power are respectively produced at the secondary sides. Then, through sensing the polarity variation of the voltage, the two synchronous controllers individually provide a synchronous driving signal. Furthermore, the synchronous driving signals respectively drive two synchronous rectifiers to conduct alternatively, so as to rectify the induced power to the output terminal.

    • A power factor correction (PFC) circuit includes an inductor, a diode, a storage capacitor, a switch and a control unit. The input power has a voltage fluctuation V1. The storage component absorbs a first voltage fluctuation and a switch regulation circuit absorbs a second voltage fluctuation V2. Thus output voltage from the PFC circuit is not a conventional constant voltage but a voltage of a great ripple. The PFC circuit further has a harmonic regulation unit. The harmonic regulation unit generates a voltage signal containing 3rd harmonic. The control unit receives a feedback signal and the voltage signal containing 3rd harmonic to generate a reference to the inductor current. Therefore, the inductor current contains 3rd harmonic. Thus power fluctuation absorbed and released by the capacitor is smaller. As a result energy storage capacitance can be reduced significantly.
    • 功率因数校正(PFC)电路包括电感器,二极管,存储电容器,开关和控制单元。 输入功率具有电压波动V1。 存储组件吸收第一电压波动,开关调节电路吸收第二电压波动V2。 因此,来自PFC电路的输出电压不是常规的恒定电压,而是具有很大纹波的电压。 PFC电路还具有谐波调节单元。 谐波调节单元产生包含三次谐波的电压信号。 控制单元接收反馈信号和包含三次谐波的电压信号以产生对电感器电流的参考。 因此,电感电流包含三次谐波。 因此,由电容器吸收和释放的功率波动较小。 因此能够显着降低储能电容。

    • In a power converter having m=two or more channels of power factor correction (PFC) circuits connected in parallel and an electromagnetic interference (EMI) filter connected in series therewith, phase shifts in switching between the respective PFC channels can allow increase of EMI filter corner frequency allowing reduction of size and cost of the EMI filter at some switching frequencies. Asymmetrical phase shifts (other than 360°/m) such as 360°/2m and other phase shifts and variations in m allow increase of EMI filter corner frequency at switching frequencies where symmetrical, 360°/m phase shifts provide no benefit to EMI filter design by providing cancellation or partial cancellation of different harmonics of the switching noise; which cancellation may be arranged to be complementary to the EMI filter function at more than one peak of the noise spectrum. (Such asymmetrical phase shifts do not significantly increase ripple and consequent switching noise). Alteration of m and corresponding alteration of phase shift may be performed adaptively for purposes of improving efficiency at light loads and the like.

    • An automatic tilt speaker has a first subassembly of a speaker unit enclosing an ordinary speaker element. The speaker unit includes a cone-shaped housing having an inner cavity for holding the speaker with its frame or basket fitted snugly in an annular frame. The housing of the speaker unit is pivotally connected to the frame by a pivot arm. The speaker housing has an arcuate exterior wall extending in a radius centered about the pivot connection of the frame. Centrally of the arcuate wall, there is a gear arch, which comprises a vertical column of horizontally elongated teeth extending substantially coplanar with the arcuate wall. On the annular frame at the diametrically opposite side of the pivot connection a tilting system is operatively connected with the teeth. The tilting system includes a motor with a reduction gearbox for driving a worm gear, which in turn drives the gear arch. The annular frame also supports a relay-based motor control board for controlling the polarity and power to the motor. Combined with the power control is a position sensing system including three slight ramp surfaces on the arcuate wall of the speaker unit which translates into three segmented tilting angles to be remotely selected to the user's listening preference.
