Rancang Bangun Unipolar PWM Dilengkapi dengan Pengaturan Frekuensi Menggunakan Operational Amplifier
Journal Title: Jurnal Ecotipe (Electronic, Control, Telecommunication, Information, and Power Engineering) - Year 2019, Vol 6, Issue 1
Abstract
Pulse Width Modulation (PWM) is applied to power electronic circuits for the control of converter circuits. In order to obtain good performance, the frequency of the PWM pulse must be adjusted to the type and parameter of the converter. In this study, the PWM pulses generated are unipolar PWM. Pulses are obtained by using three main circuits, namely triangular wave generator, control voltage and comparison circuit. The main component used is Operational Amplifier (Op-Amp). The resulting circuit can generate unipolar PWM pulses with frequency range 30 Hz to 5 kHz.
