“…Dari ketiga tipe komutasi paksa, kontrol modulasi lebar pulsa atau Pulse Width Modulation (PWM) merupakan tipe kontrol yang sangat baik digunakan untuk meningkatkan faktor kerja penyearah dan mengurangi harmonik arus masukan [8][9][10]. Karena tipe kontrol PWM dapat dinyalakan dan dimatikan beberapa kali setiap setengah siklus.…”

AbstrakPenelitian ini bertujuan untuk membandingkan pengaruh tipe penyalaan kontrol jarak sama dan kontrol sudut sama pada penyearah tiga phasa terkendali dengan melihat harmonisa yang ditimbulkan pada input tegangan. Kemudian menghitung efisiensi penyearah dan perbandingan faktor kerja dari kedua tipe kontrol tersebut. Rangkaian penyearah menggunakan filter pasif dengan beban tahanan sebesar 11 ohm dan dianalisis dengan menggunakan simulasi program PSPICE versi 7. Hasil penelitian menunjukkan bahwa penggunaan kontrol jarak sama menimbulkan harmonisa arus masukan pada orde ke-5 dan ke-7 sedangkan pada kontrol sudut sama menimbulkan harmonisa pada orde ke-3, 5 dan ke-7. Pada sisi keluaran tipe kontrol jarak sama menimbulkan riak tegangan pada orde 6, sedangkan pada tipe kontrol sudut sama menimbulkan riak tegangan pada orde ke-2 dan ke-6. Hasil perhitungan riak tegangan yang terjadi sebesar 3,5% dengan efisiensi 99,8% pada kontrol jarak sama, sedangkan pada kontrol sudut sama diperoleh riak tegangan sebesar 4% dengan efisiensi 99.7%. Selanjutnya pada sudut penyalaan 30 0 diperoleh input THD sebesar 50,26% dengan faktor kerja sebesar 0,89 pada tipe kontrol jarak sama, sedangkan pada tipe kontrol sudut sama diperoleh input THD sebesar 53,831% dengan faktor kerja sebesar 0,87. Dari hasil ini menunjukkan bahwa penyalaan thyristor dengan tipe kontrol jarak sama lebih baik dibandingkan dengan tipe sudut sama. AbstractAnalysis of three phase controlled rectifier with the same distance control as compared to the same angle control. This research aim to compare the firing of the same distance and the same angle control at three phase controlled rectifier with seen generated harmonic at input (AC side). Then calculate of rectifier efficiency and power factor comparison from both the control type. The rectifier use passive filter with resistance 11 ohm and is analysed with program simulation using PSPICE version 7.1. Result of research indicate that use of the same distance control generates the 5 th and 7 th harmonics, while the same angle control generates the 3 rd , 5 th and 7 th harmonics at the input (AC side). At the output (DC side), the same distance control type generates the 6 th voltage ripples, while the same angle control generates the 2 nd , and 6 th voltage ripples. The result of calculation of voltage ripples that happened equal to 3.5% with efficiency 99.8% at same distance control, while at the same angle control obtained voltage ripples equal to 4% with efficiency 99.7% . At the firing angle 30 0 obtained by THD input equal to 50.26% with power factor equal to 0.89 at same distance control type, while the same angle control obtained by THD input equal to 53,831% with power factor to 0,87. From this result indicate that the firing of thyristor with the same distance better then is the same angle control.

“…Their advantages have been proved to be useful in AC machine current control [17,15,5], and grid-connected current control, in both SISO and MIMO 10 plants [ 21,7,14]. A common feature of these proposals is the resistive-inductive dynamical characteristic, from the current control point of view, of the system the power converter is facing, being it a consequence of the RL EMI filter or of the equivalent circuit of, for example, an electric machine.…”

This paper proposes a new approach to control the grid-side current of LCL-grid connected voltage source converters using hysteretic relay feedback controllers.The closed loop system is stabilized by designing a local feedback around the relay element. The compensator allows the use of relay feedback controllers by making the controlled plant almost strictly positive real. The article proposes the use of the locus of the perturbed relay system as analysis and design tool and studies orbital stability for several plant and controller conditions. The approach is validated by means of simulation testing.

“…But the actions like overshooting and switching frequency is totally depending upon the above said parameters. Among the various PWM technique and boundary control methods, Hysteresis Band control is very popularly used as it is easy to implement [3]. Again it plays a vital role in maintaining the output voltage but ripple cannot be affected, thus by making the system robust [2].…”

In this paper, a new topology of Adaptive Hysteresis Band controller for Boost & Buck converter has been proposed, modeled and analyzed. The difficulties caused in Hysteresis Band (HB) controlled dc-dc converter have been eliminated using Adaptive Hysteresis Band (AHB) controller. This novel control topology can be able to maintain the switching frequency constant unlike HB controller. Thus the filter design for the converters will become easier with this controller. Again this control methodology is a robust one as it depends upon the system parameters where there was no possibility with HB controller. The Mathematical modeling of the controller is shown in this paper, further this has been simulated using Matlab /SIMULINK to generate pulse. The steady state analysis to find the parameters and the stability condition of the converter using the dynamic behavior is also portrayed in this paper. The simulation for a Boost and a Buck converter is also shown separately using AHB controller. Keyword:DC-DC power conversion Adaptive hysteresis band controller Modeling Robust control Simulation
