It is important to clarify that there is no widely recognized standard textbook specifically titled "Power Electronics with MATLAB" authored solely by Ashok Kumar. power electronics with matlab ashok kumar pdf new

However, there is a very popular textbook often used in conjunction with this topic: "Power Electronics" by P.S. Bimbhra, which is frequently supplemented by guides or lab manuals written by authors like Ashok Kumar or R.S. Singh that utilize MATLAB/Simulink.

Additionally, Ashok Kumar is a common name for authors of engineering lab manuals and practical guides (such as those published by S.K. Kataria & Sons or I.K. International).

Here is a helpful guide on what you should look for in a "Power Electronics with MATLAB" resource, how to use it effectively, and what key concepts you will learn. The textbook Power Electronics with MATLAB by L

Why "Power Electronics with MATLAB" is Indispensable

6. Important Note on Copyright

While many older lab manuals and guides are available on university websites, downloading copyrighted books via unauthorized PDF repositories is generally illegal. If the book is a published textbook, consider purchasing it or checking if your university library has a digital subscription (like IEEE Xplore or ScienceDirect) that provides legal access.

Step-by-Step Example from the Book (Simulating a Boost Converter)

To illustrate the practical brilliance of this resource, let's summarize a typical example found in the new PDF of Ashok Kumar’s book.

Problem: Design a boost converter that steps up 24V DC to 48V DC at 100kHz switching frequency with a 50W load. Why "Power Electronics with MATLAB" is Indispensable 6

Steps from the book:

  1. Open Simulink → New Model → Simscape → Electrical → Specialized Power Systems.
  2. Place Components: DC Voltage source (24V), inductor (L=150µH), IGBT, diode, capacitor (C=47µF), and resistive load (46.08Ω for 50W).
  3. PWM Generator: Use a pulse generator set to 100kHz with a duty cycle calculated as D = 1 - (Vin/Vout) = 1 - (24/48) = 0.5.
  4. Simulation Settings: Set solver to ‘ode23tb’ (stiff) with a max step size of 1e-7 seconds to capture switching transients.
  5. Run & Analyze: Observe the output voltage settling at 48V with a 1% ripple. The inductor current shows a triangular waveform—classic CCM operation.

The new edition adds a comparison of output when using an ideal switch vs. an IGBT with snubber, highlighting turn-off tail current losses.
