Abstract: A circuit breaker apparatus (32) comprises one module (30) or a plurality of series-connected modules (30), the or each module (30) including: first and second conduction paths (34, 36); and first and second terminals (38, 40) for connection to an electrical network (42), each conduction path (34, 36) extending between the first and second terminals (38, 40); the first conduction path (34) including a first vacuum switching element (52) to selectively close to allow current to flow between the first and second terminals (38, 40) through the first conduction path (34) in a first mode of operation, or open to block current from flowing between the first and second terminals (38, 40) through the first conduction path (34) in a second mode of operation; the second conduction path (36) including a second vacuum switching element (56) to selectively open to block current from flowing between the first and second terminals (38, 40) through the second conduction path (36) in the first mode of operation, or close to allow current to flow between the first and second terminals (38,40) through the second conduction path (36) in the second mode of operation, wherein the first and second vacuum switching elements (34, 36) define a break-before-make switching arrangement; the second conduction path (36) further including a primary energy storage device (74) to oppose current flowing between the first and second terminals (38, 40) through the second conduction path (36) in the second mode of operation; and the or each module (30) further including a commutation circuit (72) to establish a resonant current in the first vacuum switching element to quench an arc current appearing across the first vacuum switching element (52) in the second mode of operation.

Abstract: An alternate arm converter includes at least one converter limb that defines first and second limb portions. Each limb portion includes at least one director switch connected in series with a chain-link converter between one of two DC terminals and an AC terminal of the converter. The chain-link converters are operable to generate a voltage waveform at the AC terminal, and the director switches are operable to switch the respective chain-link converters in and out of circuit between the respective DC terminal and the AC terminal. The converter also includes a controller configured to selectively control the switching of each director switch to form a current circulation path including each limb portion and the DC network. The controller, during formation of the current circulation path, forces an alternating current to flow through the current circulation path to transfer energy between the chain-link converters of the limb portions.
