摘要：A modular power converter (10) comprises: a first terminal (12, 14) for connection to a first electrical network (24); a second terminal (18) for connection to a second electrical network (26); at least one module (28) connected between the first and second terminals (12,14,18), the or each module (28) including at least one switching element (30) and at least one energy storage device (32), the or each switching element (30) and the or each energy storage device (32) in the or each module (28) combining to selectively provide a voltage source, the or each switching element (30) in the or each module (28) being switchable to transfer power between the first and second terminals (12,14,18); and a control unit (34) being configured to selectively control switching of the or each switching element (30) in the or each module (28) to store energy from or release energy to either or both of the first and second terminals (12,14,18) so as to decouple respective power flows at the first and second terminals (12,14,18) and thereby inhibit a modulation of power flow at one of the first and second terminals (12,14,18) from modifying a power flow at the other of the first and second terminals (12,14,18).
