DSVPWM-Based SSO-PIDR Control Scheme for Indirect Matrix Converter with Unity Power Factor Under Unbalanced Grid Voltage Condition
Indirect matrix converter (IMC) is a direct ac-ac conversion system that not requires electrolytic or bulky capacitors. This system has a four-quadrant operation with input power factor control and also generates sinusoidal waveforms for output voltage with variable frequency and amplitude. For ideal operation, the rectification stage must be able to produce + ive dc-link voltage and sinusoidal input current with unity Grid Power Factor (GPF) even under an unbalanced voltage condition. Therefore, Shark Smell Optimization (SSO)-based Proportional Integral Derivative Resonant (PIDR) controller is proposed to operate the IMC switches to attain unity GPF and to maintain a balanced load voltage. The incorporation of derivative control with the existing Proportional Integral Resonant controller reduces the overshoot of the system and thus improves the transient response. Furthermore, the SSO algorithm helps to optimally tune the gain parameters of the PIDR controller. Finally, the 3-phase balanced output voltages with the preferred frequency and magnitude is produced using Double Space Vector Pulse Width Modulation technique. The results from analysis and experimental results illustrate that the system stability and the performance are improved.
