1. Getting Started: The Environment

A good guide will start by introducing the Simulink interface. You need to familiarize yourself with:

• The Library Browser: Where you find blocks.
• Simscape > Electrical > Specialized Power Systems: This is the core library for Power Electronics.
• powergui: This is the most critical block. Every circuit simulation must have this block to calculate circuit states.

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.

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.

Guide: Power Electronics with MATLAB/Simulink

If you are studying power electronics, the goal is to understand how to convert electrical energy (AC to DC, DC to AC, etc.) efficiently. MATLAB/Simulink is the industry standard for simulating these circuits before building them. Power Electronics with MATLAB by Ashok Kumar: A
