  • It will not work… if you look at a simple AC to DC converter (half-wave rectifeir) the output will either be 0 volts or equal to the input voltage-losses depending on how you polarized the DC source.

    In another circuit (full wave rectifier), the diodes will be polarized such at two will allow current flow. output = input - conduction losses

    If the rectifier is something more complex (12 pulse rectifier)… this circuit relies on transformers. If you put DC on the primary of the transformer then the output will be 0 volts and thus the rectifier output will also be 0 volts.

    I’m less knowledgeable of more elegant rectification methods (such as active rectification)…

    Interestingly… the fundamental DC to AC converter (inverter) is the same circuit as the full wave rectifier, with the diodes replaced with controllable switches (SCRs, IGBTs, IGCTs, MOSFETs, ect.)
