Abstract

An AC-AC converter (1, 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, 1j, 1m, 1n) and a power supply system (9) are provided. The AC-AC converter (1, 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, 1j, 1m, 1n) of the present disclosure includes a first AC terminal (2) with two sub terminals (21, 22), a second AC terminal (3) with three sub terminals (31, 32, 33), and a first bridge arm (4) with two switch assemblies (41, 42). The AC-AC converter (1, 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, 1j, 1m, 1n) receives and converts the input power between two wires and three wires. The two switch assemblies (41, 42) are activated, and bidirectional power flow is allowed. The two switch assemblies (41, 42) are performed as a voltage source for supporting both balanced and unbalanced loads. Both active and reactive power are also supported. Moreover, the AC-AC converter (1, 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, 1j, 1m, 1n) of the present disclosure has the advantages of reducing weight, size and cost, and enhancing conversion efficiency.
