SUMMARY
Connecting multiple transformers with identical secondaries in parallel can theoretically double the current while maintaining the same voltage. However, this practice is strongly discouraged due to the risk of circulating currents caused by slight differences in winding impedance, which can lead to overheating. Instead, transformers should be connected in series if insulation limits are not exceeded. It is critical to understand that power distribution in parallel transformers is inversely proportional to their impedances, making mismatched transformers potentially hazardous.
