摘要： A power factor corrector raises power factor at low loads or high mains voltages by modifying the switch timing or the current received by the power converter. It achieves this by increasing the switch-on time of a control switch during the falling time so that the majority of the switch-on time during a mains period occurs during the falling time, to thereby control the current received by the converter to compensate for current received by the intermediate filter. Some embodiments may employ a feedback system to produce one or more error signals that modify the control signal used to control the operation of the converter. Various embodiments may also include additional stages that limit the compensation range of the error signal.

In one embodiment, the device for driving an under damped VCM actuator comprises a first generator operable to read a first manufacture data from an image signal processor (ISP) and to generate a half natural period, ½ Td, of the VCM actuator by selecting a value approximate to the first data in a first table of the device, a second generator operable to read a second manufacture data from the ISP and to generate the maximum overshoot, K, of the VCM actuator by selecting a value approximate to the second data in a second table of the device, an input shaping signal generator operable to read an input signal corresponding to a desired camera lens moving distance from the ISP and to generate a shaping signal according to the value of the half natural period and the maximum overshoot. The input shaping signal may be produced from second order, third order and fourth order input shaping function. The present invention also provides a simple implementation of a driver configuration to achieve a fast camera lens focus speed, yet robust to tolerate actual system deviation from a manufacture design.

摘要： Various exemplary embodiments relate to a power factor corrector for low loads and a related method. The power factor corrector raises power factor at low loads or high mains voltages by having the a greater amount of current delivered to the load during the falling time of the absolute value of the mains AC voltage than during the applicable rising time. Various embodiments achieve this by increasing the switch-on time of a control switch during the falling time so that the majority of the switch-on time during a mains period occurs during the falling time. This may involve using a timing voltage increasing over a period within each half mains cycle to increase the switch-on time of conversion cycles in the falling time. This may also involve shifting the power conversion in time domain during each half mains cycle so that a majority of the time occurs during the falling time. Various embodiments may employ both methods.
摘要翻译：各种示例性实施例涉及用于低负载的功率因数校正器和相关方法。功率因数校正器在低负载或高电源电压下提高功率因数，通过在电源交流电压绝对值的下降时间内比在适用的上升时间内更多的电流传送到负载。各种实施例通过在下降时间期间增加控制开关的接通时间来实现这一点，使得在电力周期期间的大部分接通时间在下降时间期间发生。这可能涉及使用在每个半电源周期内的周期上增加的定时电压以在下降时间内增加转换周期的接通时间。这也可能涉及在每个半电源周期期间在时域中移动功率转换，使得大部分时间在下降时间内发生。各种实施例可以采用两种方法。
