摘要： A grid-side transformerless power conversion system configured to perform power conversion between a power grid and a load, the transformerless power conversion system includes a first converter, a first filter, and a second converter. The first converter is configured to convert first AC power provided from the power grid into DC power. The first converter includes a first converter module and a second converter module coupled to the first converter module to form a nested neutral point piloted topology. The first filter is coupled between the power grid and the first converter. The second converter is coupled to the first converter. The second converter is configured to convert the DC power into second AC power and provide the second AC power to the load.

摘要： An electrical energy storage module is provided. The storage module includes a reversible electrical energy conversion device intended to be connected to an electrical energy source and an electrical energy storage device. The storage device includes a first branch including two filter capacitors in series, and a second branch including two identical electrical energy storage means connected in series. A node common to the two capacitors and a node common to the two energy storage means are coupled by an impedance. A first end of the first and second branches is connected to the electrical energy conversion device, and a second end of the first and second branches is connected to the electrical energy conversion device.
