摘要:
An alternating current (AC) line emulator includes an AC power supply and an automatic regulating load. The AC power supply is used for providing an AC line frequency and an AC line voltage. The automatic regulating load is coupled between the AC power supply and a grid-connected power generation system for functioning as a test load of the grid-connected power generation system, and preventing current from reversing to the AC power supply and shutting down the AC power supply. When the grid-connected power system is tested, power consumption of the automatic regulating load is equal to a sum of output power of the grid-connected power generation system and output power of the AC power supply.

An inverter includes a first half period circuit, a second half period circuit, a first inductor, and a second inductor. A DC voltage source is used for providing a DC voltage. A loop of the first half period circuit and the first inductor is used for converting the DC voltage into a first half period of an AC voltage of an AC voltage source, and modulating a shape of the first half period of the AC voltage according to a second clock. A loop of the second half period circuit and the second inductor is used for converting the DC voltage into a second half period of the AC voltage, and modulating a shape of the second half period of the AC voltage according to a third clock.
