A new FPGA implementation of four- switch three- phase inverter

This paper is concerned on FPGA design for control implementations of four switch three phase inverters (B4, FSTPI). This paper is to present a space vector PWM algorithm for four switch three phase inverters (B4, FSTPI) based on the one for six switch three phase inverters (B6, SSTPI) (principle of similarity) where the ¿ß plan is divided into 6 sectors and the formation of the required reference voltage space vector is done in the same way as for B6 by using effective (mean) vectors. An SVPWM technique has been developed using the ready-to-use field-programmable gate array (FPGA) technology. High speed, very large number of components, large number of supported protocols, and addition of ready-to-use intellectual property cores make programmable devices the preferred choice of implementation and even deployment mass production quantities of Power Electronics. Matlab/Simulink is used for the simulation of the proposed SVPWM algorithm. A Field Programmable Gate Array (FPGA) From Xilinx Inc-Spartan 3E was used at the main of the control electronics. The simulation and experimental results are demonstrated.
