摘要： A stacked switched capacitor (SSC) energy buffer circuit includes a switching network and a plurality of energy storage capacitors. The switching network need operate at only a relatively low switching frequency and can take advantage of soft charging of the energy storage capacitors to reduce loss. Thus, efficiency of the SSC energy buffer circuit can be extremely high compared with the efficiency of other energy buffer circuits. Since circuits utilizing the SSC energy buffer architecture need not utilize electrolytic capacitors, circuits utilizing the SSC energy buffer architecture overcome limitations of energy buffers utilizing electrolytic capacitors. Circuits utilizing the SSC energy buffer architecture (without electrolytic capacitors) can achieve an effective energy density characteristic comparable to energy buffers utilizing electrolytic capacitors. The SSC energy buffer architecture exhibits losses that scale with the amount of energy buffered, such that a relatively high efficiency can be achieved across a desired operating range.

摘要翻译：层叠开关电容器（SSC）能量缓冲电路包括开关网络和多个储能电容器。开关网络只需要相对低的开关频率工作，并且可以利用储能电容器的软充电来减少损耗。因此，与其他能量缓冲电路的效率相比，SSC能量缓冲电路的效率可以非常高。由于使用SSC能量缓冲结构的电路不需要利用电解电容器，所以利用SSC能量缓冲架构的电路克服了利用电解电容器的能量缓冲器的局限性。利用SSC能量缓冲架构（无电解电容器）的电路可实现与使用电解电容器的能量缓冲器相当的有效能量密度特性。 SSC能量缓冲结构表现出随着能量缓冲量的增加而降低的损耗，使得能够在期望的工作范围内实现相对较高的效率。

摘要： An alternator system having an alternating current (ac) voltage source includes a switched-mode rectifier (SMR) coupled to the ac voltage source and having an output port coupled to an output of the alternator system, and a controller coupled to said switched-mode rectifier so as to provide a controlled pulse sequence synchronized with an angular rotor position of the (ac) voltage source to activate and deactivate the switched-mode rectifier. The controller further includes a PWM generator having a first input to receive a total duty ratio signal synchronized with an angular rotor position of the (ac) voltage source. The switched mode rectifiers are controlled to increase power output levels at lower speeds near idle. The controller combines improved idle speed power output levels with load matching improvements from PWM control for more efficient operation when compared to circuits using conventional control or PWM load matching control alone.
