“…But the full bridge circuit requires more active components and gate drivers and is not the best choice in terms of cost and reliability. Most of the reported switched-mode power circuits utilized in electromagnetic levitation use asymmetrical-type H-bridge converters with two switches and two diodes [27,31]. The circuit is energy efficient and is ideal for high-power applications.…”

Electromagnetic levitation is an important area of research. There is lot of applications of maglev in industry. Extensive research is going on for the last two decades throughout the world to design the latest form of the maglev system. Due to interdisciplinary nature, many aspects are still open in maglev research. The major components in an electromagnetic suspension system are (i) actuator, (ii) sensor, (iii) controller, and (iv) power amplifier. For the successful implementation for any maglev-based project, the basic knowledge of these components is necessary. In this manuscript, an extensive review of different components of electromagnetic levitation systems has been presented.

“…Power amplifiers are necessary for generating appropriate coil-currents in response to the command signal from the controller in the electromagnetic levitation system (Fig.1). Different kinds of power amplifiers have been proposed for electro-magnetic levitation [3,6,7,8,9,10]. These include magnetic amplifiers (which are now obsolete) as well as the more modern type of solid-state amplifiers.…”

“…The single switch based power circuit ( Fig.6) may be suitable form of switched mode power amplifier for single and multi-magnet based levitation system. A comparative study has been made between these different topologies based on their structure, working principle and experimental results [7]. In this work, a comparison between the dynamic performances for these power amplifiers have been established based on both time and frequency response analysis utilizing PSPICE tool.…”

PSPICE is a general-purpose analog and digital electronic circuit simulator. It is a powerful program that is used in IC and board-level design to check the integrity of circuit designs and to predict circuit behaviour. The DC electromagnetic levitation system (EMLS) critically deserves very fast response and the DC-DC switch mode power amplifiers used for such applications have important role to meet this demand. The coil current for the magnets used in EMLS needs to be precisely controlled to meet the attractive force demand and this calls for a fast DC to DC power amplifier that can be controlled in a closed loop fashion. The main objective of this paper is to compare the dynamic performances between these different power amplifiers so that an insight can be made about the selection of power amplifier where speed of response and bandwidth is the prime criterion. The effect of different parameters of chopper amplifier (input DC link voltage, duty cycle and switching frequency) and levitation system (resistance and inductance of magnet coil) on the dynamic responses of amplifiers also been observed both by time and frequency response analysis utilizing PSPICE. This will lead to an inference for the design and development of chopper amplifier and DC EMLS. Experimental results to show the difference in dynamic responses between selective power circuits have also been presented.
