“…The modulation used for the operation of the inverter is called unipolar sinusoidal pulse width modulation (SPWM). It has a triangular carrier signal and two reference sinusoidal signals out, phased 180° between them [8,9]. These signals will be determined by the duty cycle that each delivery D, 1-D, D1, and 1-D1 sends to the switching devices S1, S2, S3, and S4, respectively.…”

This paper presents a detailed implementation of a current source inverter using unipolar sinusoidal pulse width modulation. This method is uncommon in these types of inverters and the semiconductor devices, integrated circuits, sensors, and filters used in conjunction with the TMS320F28379D microcontroller will be discussed. The inverter was tested in both an open and closed loop with a proportional resonant controller. Satisfactory results in terms of the harmonic distortion factor at the voltage output and the regulation indices for lineal loads were obtained. The response circuit demonstrated its viability for the subsequent connection to an electrical distribution network.

“…Proses penyulutan IGBT dapat bekerja secara bergantian berdasarkan trigger SPWM yang masuk ke driver inverter oleh mikrokontroller. SPWM adalah jenis PWM yang dibangkitkan dengan cara membandingkan sinyal segitiga (carrier) dan sinyal sinus (refference) [9]. SPWM terdiri atas dua jenis, yaitu Bipolar SPWM yang memiliki satu sinyal referensi/sinus dan Unipolar SPWM yang memiliki dua sinyal referensi [10].…”

Kasus pemadaman listrik bergilir sudah menjadi masalah umum di Indonesia. Kebutuhan listrik semakin memuncak karena penggunaan energi listrik dapat menghidupkan berbagai peralatan rumah tangga dan industri. Saat ini, banyak terjadi pemadaman listrik secara bergilir karena kapasitas beban sudah melebihi kapasitas yang sudah ditentukan. Akibatnya, pasokan energi listrik menjadi tidak stabil, sehinga berdampak pada peralatan listrik rumah tangga.Akibat pemadaman listrik yang tidak menentu maka digunakan pemasok cadanan yang dapat bekerja ketika sumber daya utama tidak aktif atau disebut UPS (Uninterruptible Power Supply). UPS dapat menjadi energi cadangan listrik sementara pada saat terjadi pemadaman listrik sehina mengurangi dampak pada peralatan listrik rumah tanggaPada perancangan sistem ini, digunakan sumber solar cell 300WP(watt peak) yang digunakan untuk proses pengisian baterai 48V DC 45Ah dengan menggunakan buck-boost converter. Ketika sumber utama PLN tidak aktif ATS(Automatic Transfer Switch) secara otomatis akan memindahkan catu daya dari baterai. Dari sumber baterai digunakan inverter satu fasa untuk mencatu beban rumah tangga sebesar 50W 220V AC.

“…Internal voltage control can be achieved by controlling the conduction period of the switching elements in the inverter, which is also called as Pulse Width Modulation. In majority of the inverters, most commonly employed harmonic reduction method is Pulse Width Modulation (PWM) [1][2]. To deliver controlled voltage at the inverter output terminals, the switches must be ON and OFF with high frequency, hence fully controlled switches like IGBTs are considered for many medium voltage applications.…”

Inverter is an interface device between a dc source and ac loads which converts DC voltage to a variable voltage, variable frequency AC voltage. While converting, it introduces harmonics in the output of the system which results in additional heating of induction motors. Hence in order to diminish these harmonics, different techniques are introduced viz. external and internal control techniques in which the latter is more efficient. Out of the all proposed methods, the internal control of inverter which is also called as Pulse Width Modulation (PWM) can be achieved either using unipolar modulation technique or bipolar modulation technique. In this paper, the control circuitry to model unipolar and bipolar modulation methods is simulated and their performance is checked on an induction motor and compared in MATLAB Simulink environment.
