“…The peak-to-peak inductor current or current ripple is expressed by substituting ( 26) and ( 19) to (17) or (18). Note that the inductor current rose and fell every half of the switching frequency thus the absolute value of the inductor current ripple for both ST and NST states are identical.…”

“…Unfortunately, the dc voltage generated by this energy source is very low and is highly dependent on the level of solar irradiation. In the case of AC mains connection, additional devices are needed which generally consist of a dc-dc converter and inverter [12]- [17]. The dc-dc boost converter is traditionally used to first convert the input low dc voltage to sufficient high dc voltage needed for the inverter to subsequently transform it to ac voltage required by AC grid.…”

The increasing demand and widespread of renewable energy inherently compel the development of power electronics converter as an interface between consumers and the energy source/s. This paper presents a new two switched-impedance networks qZSI converter called High Ratio Two Switched-impedance quasi-Z-Source Inverter (HR2SZ-qZSI). Compared with the previous topology, this proposed HR2SZ-qZSI topology can achieve higher voltage gain with lower shoot-through duty ratio, and a higher boost factor. This paper also discusses comparative analysis between the previous topology and the proposed HR2SZ-qZSI topology. Furthermore, the simulation and experimental data are presented to prove the theoretical analysis of the proposed HR2SZ-qZSI topology. Despite the additional components needed, it accentuates that this proposed converter retains all features of qZSI: common ground point between the dc source and converter and smooth input current operation. Furthermore, almost all the devices rating including capacitor and diode voltage, and inductor current ripple are lower than the preceding relevant two switched-impedance qZSI family. Accordingly, this proposed HR2SZ-qZSI clearly a good power conditioning alternative for renewable generation system.

“…Pada pengaturan kecepatan motor induksi 3 fasa dengan mengatur tegangan sumber, kecepatan motor induksi 3 fasa dapat diatur apabila dalam keadaan berbeban, torsi yang dihasilkan motor semakin besar dengan semakin besarnya tegangan sumber [3]. Tetapi dengan mengatur tegangan sumber yang terlalu besar dapat mengakibatkan terjadinya fenomena saturasi pada fluks [4].…”

Berkurangnya cadangan minyak dunia mendorong penelitian dalam menemukan energi terbarukan. Perkembangan teknologi diberbagai bidang turut mendukung adanya penelitian tersebut. Mobil listrik menjadi solusi untuk mengurangi ketergantungan terhadap penggunaan minyak bumi tersebut. Dalam penerapannya, mobil listrik digerakkan menggunakan motor induksi 3 fasa. Pada pengaturan tegangan dan frekuensi motor induksi 3 fasa, memiliki kelebihan dan kekurangan. Sehingga dibutuhkan suatu metode untuk mengoptimalkan pengaturan kecepatan motor induksi 3 fasa pada pengaturan tegangan dan frekuensi. Inverter 3 fasa yang dipakai menggunakan metode Sinusoidal Pulse Width Modulation (SPWM), pengaturan kecepatan dilakukan melalui pengaturan frekuensi output dan tegangan output pada inverter 3 fasa. Motor induksi 3 fasa yang dipakai memiliki daya sebesar 1.5 HP dengan tegangan 220 Vrms yang dihubung secara delta. Pengontrolan kecepatan motor induksi 3 fasa dapat dilakukan dengan beberapa cara salah satunya adalah scalar control atau biasa disebut juga kontrol tegangan/frekuensi (v/f). Prinsip dari scalar control ini memaksa motor memiliki hubungan yang konstan antara tegangan dan frekuensi, sehingga pengaturan kecepatan motor melalui tegangan dan frekuensi lebih optimal. Dengan perubahan nilai ma (modulation amplitude) dan nilai mf (modulation frequency) pada inverter 3 fasa, pada saat perbandingan ratio tegangan dengan frekuensi 220/50 maka dibutuhkan 322.6 VDC. Dengan kecepatan putar motor 1462 RPM

“…The scalar control is called a conventional control due to the easy way to control the IM. Lately, scalar control has been widely applied to the industry, transportation, and household sectors with an industrial class instrument [6]- [7]. The scalar control of the stator voltage depends on frequency supply, except in low and above base rotor speed [8]- [9].…”

Nowadays, the Internet of Things (IoT) is inseparable from the industrial revolution 4.0 and society 5.0. IoT allows all aspects to be connected at the same time. In industrial processes, the IoT controls the actuator and monitors the behavior system. Industrial IoT (IIoT) connected the Human Machine Interface (HMI) Haiwell C7S with the actuator (Schneider Altivar 12) and the controller (OMRON CP1E-NA20DRA). The communication between the variable speed drive and Haiwell C7S using Modbus protocol is connected with RS485. Schneider Altivar 12 is a variable-speed drive that controls the Induction Motor (IM) rotor speed using the conventional V/F method. The scalar control of IM controls supply frequency and voltage simultaneously. The success parameter of the proposed systems is a rotor speed response and voltage in various supply frequencies. The results show that the 5 Hz supply frequency makes the absolute error of rotor speed response 11.43% for tachometer measurement, 0.67% from VSD data, and 12.67% for rotary encoder measurement. This absolute error will decrease significantly when the supply frequency exceeds 20 Hz, or the rotor speed response exceeds 1200 rpm. The changes in the supply frequency change the voltage's magnitude. The voltage will increase proportionally, along with the increase in supply frequency.
