MODULE

摘要

A module for use in a voltage source converter includes: first and second terminals; an energy storage device; at least one switching element to switch the energy storage device into or out of circuit with the terminals to selectively provide a voltage source; and a voltage-limiting component and/or a resistive element. The switching element(s) are switchable to selectively form a current path that passes through the voltage-limiting component and/or the resistive element and are further switchable to selectively switch the energy storage device into or out of circuit with the voltage-limiting component and/or the resistive element. The module includes electrical blocks including first and second pairs of electrical blocks connected in parallel with the energy storage device in a full-bridge arrangement. Each of the electrical blocks include a switching element, and one of the electrical blocks includes the voltage-limiting component and/or the resistive element.

1. A module for use in a voltage source converter comprising:
first and second terminals for connection to an electrical network; an energy storage device; at least one switching element, the or each switching element being switchable to switch the energy storage device into or out of circuit with the first and second terminals to selectively provide a voltage source; and a voltage-limiting component and/or a resistive element, the switching element or at least one of the switching elements being switchable to selectively form a current path that passes through the voltage-limiting component and/or the resistive element, the switching element or at least one of the switching elements being further switchable to selectively switch the energy storage device into or out of circuit with the voltage-limiting component and/or the resistive element, wherein the module includes a plurality of electrical blocks arranged as first and second pairs of electrical blocks, the first and second pairs of electrical blocks being connected in parallel with the energy storage device in a full-bridge arrangement, each of the plurality of electrical blocks including a switching element, at least one one of the plurality of electrical blocks including the voltage-limiting component and/or the resistive element.
