Design of Type-III controller for dc-dc switch-mode boost converter

Abstract

DC-DC power converters have played a key role for different fields applications. Such demanding applications have been required a steady source of voltage irrespective any changes in line and load. The steady-state behaviors of these power-supplies have been defined by the converter topology. But the controller has taken place an important role for maintaining the accurate transient i.e. dynamic performance in dc-dc powersupplies. Some dc-dc power-supplies like boost, buck-boost etc have a right-half-plane zero i.e. there is a problem of nonminimum phase, so it is difficult for the PID controller to exhibit good performance. For this reason a special kind of classical controller i.e. Type-III controller is introduced for obtaining better performance. This paper describes the designing of a Type-III controller for a dc-dc switched-mode boost converter.

Design and implementation of type‐II and type‐III controller for DC–DC switched‐mode boost converter by usingK‐factor approach and optimisation techniques

“…These poles-zeros combination provide maximum phase boost 180°at the crossover frequency. The relation between 'k' and the phase boost of this controller can be written as follows [10] k = tan phase boost 4…”

“…have a problem of non-minimum phase (initial undershoot) due to the presence of a right-half-plane (RHP) zero in their plant transfer function [4,5], hence it is troublesome for PID controller to show the good performance with line, load variations and parametric uncertainty. For this reason type-controllers [6][7][8][9][10][11] are best suited. In the proposed work, the design of Type controllers have been aimed by using 'k-factor' approach and then controller parameters have to be optimised further by using different optimisation techniques for obtaining better stability and performance for a DC-DC switched mode boost converter.…”

Phase-Shift PWM Converter with Wide Voltage Operation Capability

“…The voltage regulator TL431 and optocoupler PC817 are adopted to control the load voltage. The type 3 voltage control [29] with two zeros and three poles are used to have the enough phase margin at crossover frequency at 8 kHz. Figure 5.…”

Fuzzy Logic Control Design and Implementation with DC-DC Boost Converter

“…PLC is oppressed to control plants or industrial equipment such as water and waste regulator, energy, oil and gas purifying [7]. [8] Here, a novel topology baptized an ANFIS (Adaptive Neuro-Fuzzy Inference System) supervisor based soft swapped DC/DC converter with non-isolated joined inductor has been replicated and obtainable for refining the power of stand-alone PV system [9][10][11][12][13]. A Proportional-Integral (PI) founded Maximum-Power-Point-Tracking (MPPT) regulator procedure is projected in this study where it is practical to a Buck-Boost converter [14][15][16][17][18][19][20][21].…”
