There is provided a transformer system (10) for converting a grid voltage (Vgrid) to a regulated voltage (Vregulated) and output the regulated voltage (Vregulated) to a power line (30), the transformer system (10) comprising: a first transformer (40) configured to step down the grid voltage (Vgrid) to an unregulated voltage (Vunregulated) and provide the unregulated voltage (Vunregulated) at an output of the first transformer (40); a shunt coupling transformer (50) connected in parallel with the output of the first transformer (40) and further connected to power electronics circuitry (60); and a series coupling transformer (70) connected in series with the output of the first transformer (40) and further connected to the power electronics circuitry (60). The power electronics circuitry (60) adds, via the series coupling transformer, a conditioning voltage (Vconditioning) in series to the unregulated voltage (Vunregulated) to generate the regulated voltage (Vregulated). The first transformer, the series coupling transformer and the shunt coupling transformer are housed in a single transformer tank (80), and the power electronics circuitry is housed in a power electronics enclosure (90) separate from the transformer tank. Each of the transformer tank and the power electronics enclosure comprises one or more openings (95) through which electrical connections (97) between the shunt coupling transformer (50), the series coupling transformer (70) and the power electronics circuitry (60) pass.
A transformer system configured to convert a grid voltage from an electrical grid to a regulated voltage and output the regulated voltage to a power line, the transformer system comprising:
The transformer system of claim 17, wherein the shunt coupling transformer is connected in parallel with the output of the first transformer such that a winding of the first transformer is connected in parallel with a winding of the shunt coupling transformer, and wherein the series coupling transformer is connected in series with the output of the first transformer such that the winding of the first transformer is further connected in series with a winding of the series coupling transformer.
The transformer system of claim 17, wherein the power electronics circuitry comprises a rectifier, an inverter and a DC link capacitor, and wherein
