Abstract :
Classical PWM techniques are replaced by current source sliding mode control (SMC) deciding the IGBT´s status in real time by using a FPGA. Utility synchronization and inverter management is guaranteed by Park vector transformation. Three novel sliding strategies for current controlled PWM inverters are described, and several simulations show the performance of the inverter control
