<span lang="EN-US">This paper describes a new strategy for optimizing the switching angles of a three-phase inverter in a photovoltaic system. It presents non-traditional solutions to the problem of selective harmonic elimination (SHE) in three-phase inverter (VSI)-fed induction motor drives. The aforementioned problem was solved independently by using hybrid genetic algorithms (HGAs) and a modified Newton–Raphson method. GAs can obtain the correct solution even if the first generation is arbitrary. The solution then converges rapidly. The modified Newton–Raphson method is used to solve transcendental equations of the SHE pulses width modulation (SHEPWM) technique, which is a unique method that produces all possible solutions without assuming the initial angles. This modified technique is not complex and ensures rapid convergence to the solution. A real-time experimental verification of the SHEPWM technique was performed in the OP5600 RT-Lab simulator. The results obtained show that the proposed SHEPWM algorithm controls the fundamental voltage and effectively eliminates the desired harmonics, and that the evolution of the signal quality increases according to the modulation index. For M=1.1 the SHE-PWM gives the best result: a current THD of 5% for a switching frequency of 1150 Hz.</span>

Alat untuk mengubah daya dc menjadi daya ac disebut dengan inverter. Inti dari inverter sinusoida terletak pada kontrol switching, dimana bentuk gelombang dan frekuensi ditentukan pada alat kontrol, salah satunya adalah gelombang SPWM. Dipasaran telah tersedia pembangkit SPWM seri EGS-002, yang beroperasi pada frekuensi tetap 50 HZ atau 60 Hz, sehingga tidak bisa di gunakan untuk membangkitkan listrik dengan frekuensi variabel. Sebagai pembangkit sinyal SPWM dan penentu frekuensi variabel digunakan mikrokontroller arduino Uno. Frekuensi yang direncanakan adalah 10Hz sampai dengan 50Hz. Kontrol frekuensi direncanakan menggunakan variabel resistor. Sebagai driver switching menggunakan H-bridge jenis L-298 yang sudah tersedia dalam bentuk modul driver motor L-298 dan transformator konvensional sebagai penaik tegangan. Hasil yang telah dicapai adalah inverter yang bisa menghasilkan sinyal SPWM dengan frekuensi bisa diatur mulai 9,7Hz sampai dengan 58,14Hz melalui variabel resistor eksternal. Dan sesudah melalui tranformator/ filter akan menghasilkan sinyal sinusoida dengan frekuensi yang sama. ABSTRACT A device for converting dc power into ac power is called an inverter. The essence of the sinusoidal inverter lies in the switching control, where the waveform and frequency are determined by the controller, one of which is the SPWM waveform. In the market, there is an EGS-002 series SPWM generator, which operates at a fixed frequency of 50 Hz or 60 Hz, so it cannot be used to generate electricity with variable frequency. As a SPWM signal generator and variable frequency determinant, Arduino Uno microcontroller is used. The planned frequency is 10Hz to 50Hz. Frequency control is planned using a variable resistor. As a switching driver, it uses an L-298 type H-bridge which is already available in the form of an L-298 motor driver module and a conventional transformer as a voltage booster. The result that has been achieved is an inverter that can produce SPWM signals with adjustable frequency from 9.7Hz to 58.14Hz through an external variable resistor. And after going through the transformer / filter will produce a sinusoidal signal with the same frequency.

The switching control circuit in a DC to AC inverter is the critical part that is applied to control the power transistors insulated-gate bipolar transistor (IGBTs) and metal-oxide semiconductor field-effect transistor (MOSFETs). This paper proposes a high-performance and low-cost pulse width modulation (PWM) control signal with a 120º phase shift circuit for a two-level three-phase inverter. Typically, a PWM signal with a 120º phase shift for three-phase inverters is generated with the help of analogue components with more complicated designs and power losses or by using a microcontroller with necessary programming or coding. The proposed solution is to design a 120° three-phase shift circuit based on D flip-flops and the 555-timer to generate the clock signal for the flip-flop input in addition to the dead-time control circuit. The proposed circuit is controlled by one square wave signal as an input signal to generate six output PWM control signals at 50 Hz to operate six MOSFETs in the three-phase inverter. Simulation results in power simulation software PSIM and PROTEUS simulation tools are used to verify the proposed circuit. Hardware implementation of the proposed circuit and three-phase inverter is carried out to validate the performance of the proposed design.
