“…It is characterized by constant amplitude pulses with different duty cycle for each period. The width of this pulses are modulated to obtain inverter output voltage control and to reduce its harmonic content [2]. Nowadays, sinusoidal pulse width modulation or SPWM is the most popular method used in motor control and inverter application.…”

This paper presents theoretical and experimental aspects related to the implementation of a Digital Signal Processor (DSP) based Sinusoidal Pulse Width Modulation (SPWM) for single phase inverter. Two sinusoidal reference signals complement to each other are compared with a carrier signal to generate PWM signals for the switches. A digital SPWM algorithm is implemented in DSP TMS320F2812 using SIMULINK model constructed from blocks of the C2000 Embedded target Library. The efficiency of the inverter is high and its offers less total harmonic distortion. The proposed system is verified through simulation and is implemented in a prototype, and the experimental results are compared

“…So in the actual implementation, the software needed to be tested in the actual prototype which may lead to system failure as well as it takes so much time to obtain the optimum parameters. On the other hand, there are some studies dealing with the digital part as an actual implementation 7), 8) or comparing theoretical and experimental aspects of inverter power supply design 9) . Due to the previous work in the inverter power supply design, there are many challenges which open a wide range of research fields.…”

Inverter power supplies have been developed as an analog circuit. Over the past decade, digital control has emerged as a viable candidate for the inverter power supplies due to the benefits which can be added by applying the digital control. However the complexity of digital control has been dramatically increasing. One of the leading methods in the digital control design is the model based development technique. Modeling and simulation act as the first step of model based development technique and they are very useful for the development and implementation in both hardware and software. They can lead to improve the performance, reduce development and production cost and time. This paper constructs a Model In the Loop Simulation (MILS) environment for designing the embedded software for the inverter power supply. The principle of the operation and the key features of using the digital PWM controllers are presented. Moreover, the important software parameters are optimized using the simulator. To verify the validity of the developed model, comparisons between the circuit simulation and experimental results are shown. The illustrations show that the results obtained by the developed model are in good agreement with the experimental results.

“…Its disadvantages are it is not easy to find an appropriate sliding surface and its performance will be degraded with a limited sampling rate. A true sine single phase PWM inverter has been realized through a single chip DSP [10]. The algorithm, built in it, has served to achieve a fast control of the current in the PWM inverter.…”
