IEEE 444-1973 IEEE Standard Practices and Requirements for Thyristor Converters for Motor Drives Part 1- Converters for DC Motor Armature Supplies

IEEE 444-1973 IEEE Стандартная практика и требования к Тиристорные Преобразователи для привода Часть 1 Преобразователи для постоянного тока якоря двигателя Supplies

This standard applies to all types of line-commutated semiconductor power converters, employing monocrystalline semiconductor thyristors or diodes, when used in industrial motor drive applications requiring adjustable direct voltage for dc motor armature or field, or adjustable voltage and frequency in the case of ac motor drives (cycloconverter). While written primarily around the requirements of motor drives needing sufficient power to utilize multiphase power converters (Fig , this standard is applicable with reasonable interpretation to all line-commutated power converters used in industrial motor drive applications.
