Abstract

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.
