Currently learning verilog in digital design courses in school and would like to design a simple switching power supply and need some guidance for choosing the type of circuit to use. I've seen examples of solar inverters using transformers and the CPLD to generate sine wave. Also seen examples of Arduino/MATLAB Simulink based boost converter circuits. In car audio transformer based designs are prevalent for pre amp and amplifier supplies. Discrete IC's use boost converter and flyback converters. What are the benefits to each type of circuit for audio use?
