Control Systems for Power Electronics: A Practical Guide by Mahesh Patil, Pankaj Rodey

By Mahesh Patil, Pankaj Rodey

The scope of the booklet covers lots of the features as a primer on strength electronics ranging from an easy diode bridge to a DC-DC convertor utilizing PWM regulate. The thyristor-bridge and the mechanism of designing a closed loop approach are mentioned in bankruptcy one, and 3. The suggestions are utilized within the fourth bankruptcy as a case research for dollar converter which makes use of MOSFETs as switching units and the closed loop process is elaborated within the 5th bankruptcy. bankruptcy six is concentrated at the embedded method fundamentals and the implementation of controls within the electronic area. bankruptcy seven is a case examine of program of an embedded keep an eye on process for a DC motor. With this ebook, the reader will locate it effortless to paintings at the useful regulate platforms with microcontroller implementation. The middle reason of this e-book is to aid achieve an speeded up studying route to useful regulate method engineering and rework regulate concept to an implementable keep an eye on method via electronics. Illustrations are supplied for many of the examples with primary arithmetic in addition to simulations of the structures with their respective equations and balance calculations.

Example text

The steady-state error is a phenomenon that may be acceptable for some systems but may not be acceptable for other systems. For example, in an application like a UPS battery charger, a difference of a few volts from the desired reference may cause the system to draw excess current causing overheating of the battery. In systems where the steady-state error is not acceptable, this ‘error’ between actual output and reference can be eliminated completely by integrating the difference between reference and feedback over a period of time.

A study of the effect of the gains of the P, I, and D controllers on the overall dynamics of the closed-loop system is described below. In order to maintain the output voltage constant, the controller should adjust the duty cycle of the power switch when the input voltage or the load changes. This is achieved by the PI controller. A usual challenge in control engineering is to decide upon the starting gains for the P and I controller, which can be changed later to fine-tune the system performance.
