SVPWM Program for Three-Phase Induction Motor Drive Systems

The SVPWM program is an advanced control algorithm used for the development and application of three-phase induction motor frequency converters. This program is based on Space Vector Pulse Width Modulation technology, which involves precise calculation and control of motor current and voltage through sector determination, vector synthesis, and duty cycle computation to achieve high-efficiency motor control. The algorithm typically implements Clarke/Park transformations to convert three-phase quantities to two-phase rotating reference frames, followed by switching sequence generation using seven-segment or five-segment methods. The SVPWM program finds extensive applications in the field of motor drives, including industrial production lines, home appliances, and transportation systems. By utilizing the SVPWM program, engineers can improve motor operating efficiency, reduce energy consumption, and provide more precise control and faster dynamic response. The implementation commonly involves timer interrupts for precise switching timing and dead-time compensation circuits to prevent shoot-through faults. Therefore, the SVPWM program plays a crucial role in modern motor control systems, offering reliable motor control solutions across various industries through optimized space vector sequencing and harmonic reduction techniques.
