Multi-micro-controller-based implementation of 3-phase inverters on industrial scale

A simple, low cost design and implementation of 3-phase industrial inverter unit has been developed by employing commonly used electronic components. The unit is based on space vector modulation principle and applies the simple scalar control algorithm constant V/F. Digital hardware circuit ideas as well as software function implementation in the proposed inverter add good features to its performance. The proposed industrial unit has been tested under different operating conditions and it proofs its outstanding features. It is planned to introduce this design as a product into industry in different sectors.
