Chapter 3: AC-DC Converters (Rectifiers) - Single and three-phase controlled/uncontrolled rectifiers with R, RL, and RLE loads. Includes FFT analysis of input current harmonics.
Chapter 4: DC-DC Converters (Choppers) - Thorough simulation of buck, boost, buck-boost, and Cuk converters. The new edition adds continuous vs. discontinuous conduction mode (CCM/DCM) analysis.
Chapter 5: DC-AC Converters (Inverters) - Single-phase (half/full bridge) and three-phase voltage source inverters. Notable addition: Pulse Width Modulation (PWM) techniques (sinusoidal, space vector, and hysteresis).
Chapter 6: AC-AC Converters - AC voltage controllers and cycloconverters.

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