Three Phase Inverter

This paper presents a simplified algorithm of space vector pulse width modulation (SVPWM) for a two-level three-phase inverter, which can operate in undermodulation and overmodulation modes. In other simplifications founded in literature, the reference voltages are modified and compared with a triangular carrier to estimate the switching states of the inverter. However, this paper proposes the modification of the carrier signal instead of the references. This procedure reduces the number of mathematical operations and increases the execution speed of SVPWM algorithm in DSPs or FPGAs. The reference voltages are sinusoidal, even for overmodulation mode. Simulation and experimental results proves that the proposed simplification produces the same switching patterns than conventional SVPWM, is simpler and is faster than other simplifications.

Artikel ini menerangkan penggunaan pengawal mikro serbaguna untuk menjana denyut–denyut modulasi lebar jalur untuk penyongsang tiga fasa. Kelebihan utama teknik ini adalah keringkasan perkakasan – hanya sebuah pengawal mikro dengan peralatan dalaman sahaja diperlukan. Hasilnya adalah sebuah sistem yang ringkas, murah dan dapat dipercayai. Setelah prototaip penyongsang menggunakan pengawal mikro Siemens 80C167 telah dibangunkan dan beberapa hasil ujian diberikan. Kata kunci: Pengawal mikro; penyongsong; denyut modulasi lebar jalur; elektronik kuasa. This paper describes the use of a general purpose microcontroller to generate the pulse width modulation (PWM) pulses for a three–phase inverter. The main feature of the work is the simplicity of the hardware – only a fixed point microcontroller with its associated internal peripheral is required. This result in an extremely simple, low-cost and reliable system. A laboratory inverter prototype using a Siemens 80C167 microcontroller is developed and typical results are presented. Key word: Microcontroller; inverter; pulse width modulation; power electronics, renewable energy.

Three Phase Inverter

The inverters allow us to convert direct current into alternating current with a sine waveform. This work uses the Matlab-Simulink program to develop from a graphic and block environment a SPWM (Sinusoidal Pulse Width Modulation) modulation technique that allows generating the switching pulses of a three-phase inverter based on bridges H, a simulation of the pulses applied to the inverter is also performed to record the voltage at the output of the inverter. Finally, a programming method based on the Icestudio environment is shown to integrate and be able to physically generate the pulses from an FPGA (Field-programmable gate array). The value of this work lies in the detailed description of the procedures necessary to develop the programming of the SPWM modulation that generates the switching pulses and their integration into the FPGA.
