SYNTHESIS OF THE CONTROL LAW OF A HIGH-POWER BRIDGE VOLTAGE CONVERTER
Annotation
A modified method of phase control is developed for a high-power dc bridge voltage converter is developed. The proposed method is based on variation of power transistors switching frequency. Предложенная методика основана на изменении частоты коммутации силовых ключей. In order to improve dynamic indices characteristics of the designed system and reliability and durability of the converter it is proposed to restrict maximal current switched by transistors and to use an algorithm of PI-control law with adjustable parameters which values depend on supply voltage.
