<p>A power supply aging system and a load balance control method. The power supply aging system includes: a system balance power supply unit (201) for producing a DC current for the need of system constant current balance; a regenerating load unit (202) for converting a low DC voltage outputted by a tested unit (200) to a high DC voltage; a DC to AC converting unit (203) for converting the high DC voltage to the AC voltage needed by the tested unit. The AC voltage is transmitted to the tested unit through a regenerated AC current BUS. The system does not need any isolation transformer nor the authorization from power supplying enterprises. The system can balance the DC load sharing, reduce the cost, improve the efficiency of electrical energy feedback and reduce the energy waste.</p> |
