| 摘要 |
The present invention relates to a DC-AC inverter (200) comprising a plurality of H-bridge converters (101, 102,...), each being arranged to be integrated with a respective photovoltaic element (108, 109,...) and to be supplied with a DC voltage from the photovoltaic element, the H-bridge converters further being cascaded to produce a multilevel voltage output (Vout). The DC-AC inverter further comprises switch control circuitry connected to each one of the plurality of H-bridge converters to control switching thereof for producing the multilevel voltage output, and a central adaptation unit connected to the cascaded H-bridge converter for adapting the multilevel voltage output such that an AC grid voltage is output from the DC-AC inverter. |
