Abstract :
In PV systems grid-connected, we always have to work with power electronics modules. For safety, any design of power electronics converter should be simulated carefully in order to prevent from serious damages from high voltage, high current which can cause fire, explosion. By using hardware-in-the-loop (HIL) simulation, we could make sure the converter would operate the right way, which is not always achieve on the real hardware design when the first attempt, so that we can reduce ricks and furthermore reduce product development time and cost. After success on simulation, it will be not much complex to implement the algorithm to the real hardware. This paper presents the process for designing the HERIC inverter by using PSIM software which can be simulate and generate the project code for implement to the floating point DSP: TMS320F28335. The HERIC (Highly Efficient and Reliable Inverter Concept) inverter is used in the design because of its advantages: high efficiency and safety by reducing the leakage ground current when the inverter is connected to the national grid without using a transformer. The algorithm was executed by the chip TMS320F28335 high performance up to 150MHz with a math-optimized core. The process produced in this paper can be applied for any design idea about a high power, high efficiency power electronics converter.
