Universal power conversion devices for alternating current electric apparatus

The present disclosure is directed to universal power conversion devices for alternating current electric apparatus. One example power conversion device includes a plurality of transformers and a plurality of terminal blocks. The plurality of terminal blocks comprise at least an AC input terminal block for receiving an input alternating current signal and a primary coil terminal block. The primary coil terminal block has a plurality of output terminals respectively connected to a plurality of taps of a plurality of primary coils of the plurality of transformers. A plurality of jumpers respectively providing electrical connection between respective output terminals of the AC input terminal block and input terminals of the primary coil terminal block are selectively reconfigurable for reconfiguring a power conversion applied to the input alternating current signal by the power conversion device.
