Adaptive commutation hybrid circuit breaker

A method, comprising:

• receiving instructions to interrupt a first current through an electromechanical switch along an electrical line of a power delivery system according to a first mode or a second mode;
• instructing a second switch to electrically couple an uncoupled voltage source convertor (VSC) to the electrical line;
• regulating, via the VSC, the first current through the electromechanical switch to zero according to the first mode or the second mode;
• instructing the second switch to electrically decouple the VSC from the electrical line in response to the first current through electromechanical switch being regulated to zero;
• regulating, via one or more capacitors, a second current through the VSC to zero in response to the VSC being decoupled from the electrical line.

A non-transitory computer-readable medium comprising computer-executable instructions that, when executed, are configured to cause data processing circuitry to perform operations comprising:

• receiving a signal indicative of one or more electrical characteristics of an electrical line of a power delivery system;
• determining a fault condition based on the one or more electrical characteristics;
• transmitting first instructions or second instructions to a circuit breaker coupled to the electrical line of the power delivery system to cause the circuit breaker to:
• reduce a first current along the electrical line by coupling an uncoupled voltage source converter (VSC) to the electrical line;
• decouple the VSC from the electrical line in response to the first current being reduced to zero;
• and
• reduce a second current through the VSC to zero via one or more capacitors coupled to the VSC.
