摘要： Methods and systems for transforming electric power between two or more portals. Any or all portals can be DC, single phase AC, or multi-phase AC. Conversion is accomplished by a plurality of bi-directional conducting and blocking semiconductor switches which alternately connect an inductor and parallel capacitor between said portals, such that energy is transferred into the inductor from one or more input portals and/or phases, then the energy is transferred out of the inductor to one or more output portals and/or phases, with said parallel capacitor facilitating “soft” turn-off, and with any excess inductor energy being returned back to the input. Soft turn-on and reverse recovery is also facilitated. Said bi-directional switches allow for two power transfers per inductor/capacitor cycle, thereby maximizing inductor/capacitor utilization as well as providing for optimum converter operation with high input/output voltage ratios. Control means coordinate the switches to accomplish the desired power transfers.
摘要翻译：在两个或多个门户之间转换电力的方法和系统。任何或所有门户都可以是直流，单相交流或多相交流。转换是通过多个双向导电和阻塞半导体开关来实现的，该半导体开关在所述入口之间交替地连接电感器和并联电容器，使得能量从一个或多个输入端口和/或相位传递到电感器中，然后能量是从电感器转移到一个或多个输出端口和/或相位，所述并联电容器有助于“软”关断，并且任何多余的电感能量被返回到输入端。软启动和反向恢复也方便。所述双向开关允许每个电感/电容器周期进行两次功率传输，从而最大限度地提高电感器/电容器的利用率，并提供具有高输入/输出电压比的最佳转换器操作。控制装置协调开关以实现所需的功率传递。

摘要： The present application discloses methods, circuits and systems for power conversion, using a universal multiport architecture. When a transient appears on the power input (which can be, for example, polyphase AC), the input and output switches are opened, and a crowbar switch shunts the inductance which is used for energy transfer. This prevents this inductance from creating an overvoltage when it is disconnected from outside lines.

摘要： A cascaded switching power converter for coupling a photovoltaic (PV) energy source to power mains provides a high-efficiency and a potentially simple control mechanism for AC solar energy conversion systems. The PV energy source charges a capacitive storage element through a DC-DC converter, and an inverter couples energy from the capacitive storage element to the mains supply. The DC-DC converter is controlled so that ripple present on the capacitive storage element due to current drawn by the inverter is not reflected at the input of the DC-DC converter, which is accomplished by varying the conversion ratio of the DC-DC converter with the ripple voltage present across the capacitor. The average voltage of the capacitor can also be increased with increases in the available power output from the PV energy source, so that a corresponding increase in power is transferred to the mains supply.

An inverter receives DC power and converts the DC power to AC power to drive a load.

A soft charge circuit limits in rush current to the link capacitor. The soft charge circuit comprises an inductor in the bus and a resistor assist circuit across the inductor along with an anti-parallel clamping thyristor reverse connected also across the inductor.
