Modern metals production depends on large amounts of electrical energy. In many electro-intensive processes, however, supplying power is only the first requirement. Electrical energy must also be converted and regulated according to the specific needs of the metallurgical process.<\/span><\/span><\/p>\n

<\/span>Aluminum<\/span> smelting, copper electrorefining and the electrowinning of metals such as copper, zinc and nickel require controlled direct current<\/span>. In these applications, the <\/span>rectifier<\/span> is an integral part of the production system, influencing process stability, operational continuity, energy <\/span>consumption<\/span> and long-term plant performance<\/span>.<\/span><\/span>\u00a0<\/span><\/p>\n<\/div><\/div>

Why metals production requires high-power DC <\/span><\/span>\u00a0<\/span><\/h2>\n

Industrial <\/span>electrical<\/span> systems <\/span>generally<\/span> supply <\/span>alternating<\/span> <\/span>current<\/span>, <\/span>while<\/span> <\/span>electrochemical<\/span> metal production <\/span>processes<\/span> <\/span>require<\/span> <\/span>direct<\/span> <\/span>current<\/span> to <\/span>enable<\/span> metal <\/span>extraction<\/span>, <\/span>refining<\/span> or <\/span>deposition<\/span>.<\/span><\/span>\u00a0<\/span><\/span><\/p>\n

High-power<\/span> rectifiers<\/span><\/span><\/a> <\/span>convert<\/span> AC power into the DC output required by the process. Depending on the application, they may need to deliver <\/span>very high<\/span> current at <\/span>relatively low<\/span> voltage or combine high current and voltage to reach the required power level.<\/span><\/span>\u00a0<\/span><\/p>\n

Conversion alone <\/span>is<\/span> <\/span>not<\/span> <\/span>enough<\/span>. The <\/span>rectifier<\/span> must <\/span>also<\/span> <\/span>regulate<\/span> <\/span>its<\/span> output <\/span>as<\/span> <\/span>operating<\/span> <\/span>conditions<\/span> evolve.
