Survey of Control Methods for Dc-Dc Converters

Abstract

The paper presents a survey of the currently used control methods for DC-DC converters and the current state of research in this area. Determining the ideal method for output voltage control in DC-DC converters is a demanding task due to their nonlinear character, various types of connection, and ways of use. The currently prevailing control methods implemented in DC-DC converters are voltage-mode, current-mode and hysteretic control. Each of these methods comes with certain drawbacks, which is why there is intensive research going on aimed at more progressive DC-DC converter control methods that would replace or supplement the currently used types of control in order to increase the reliability and quality of DC-DC converters output voltage control. The paper includes a basic description of each of the control methods with focus on the principles of their function and on the main pluses and minuses of each method.

Review of Bidirectional DC-DC Converters and Trends in Control Techniques for Applications in Electric Vehicles

“…Soft-switching (SS) techniques are used to minimize switching losses in semiconductor devices [44], [60]. Phase-shift control (PS), two-edge-modulation (TEM) and space-vectormodulation (SVM) have also been proposed for converter control [75]. Sliding mode control (SMC) is a nonlinear capable method that is less affected by changes in the load [76], [77].…”

Comparative Examination of Control Strategies in DC-DC Power Converters: A Traditional and Artificial Intelligence Perspective

“…Isolated topologies utilize phase-shift to regulate power transfer [10]. Due to the high sensitivity of the derivative term in PID control, it is often omitted [15]. Experimental validation of PID for DC-DC converters has been demonstrated using microcontrollers [6,7] or FPGAs [11,16].…”

“…It was first developed in the 1950s as a way to convert direct current (DC) electricity from one voltage level to another, allowing for better control of the device's power and performance. According to previous, these devices can work effectively with electric vehicles, sustainable energy systems, airborne electronics, and many modern appliances [1][2][3][4][5][6][7]. Such a DC-DC converter can be illustrated in Fig.…”

“…Nevertheless, despite their robustness and dynamic operation range, these converters still reflect effective disadvantages in the real world which could affect the converter's performance and try to reduce its efficiency. Considering depending on the above, different methods and approaches can be adopted to reduce the impact of these defects [8][9][10]. Digital control techniques are considered one of the most effective methods to improve transformer performance such as pulse width modulation (PWM) or digital signal processing (DSP) [11][12][13].…”
