开关音响功率放大器

A switching audio power amplifier circuit. Switching audio power amplifiers are more efficient than conventional power amplifiers as switching devices are operating only in the fully-on and fully-off states. This audio power amplifier uses a 1MHz switching frequency and has a PI feedback controller to ensure that output voltage tracks the 2kHz and 2.5kHz sine wave inputs. The power spectrum is plotted in the Spectrum Analyzer, and can be used to inform selection of controller and filter parameters.

太阳能逆变器

Determine the efficiency of a single-stage solar inverter. The model simulates one complete AC cycle for a specified level of solar irradiance and corresponding optimal DC voltage and AC RMS current. Using the example model ee_solar_characteristics, the optimal values have been determined as 342V DC and 20.05A AC for an irradiance of 1000W/m^2 and panel temperature of 20 degrees Celsius. Inverter efficiency is determined in two independent ways. The first compares the ratio of AC power out to DC power in over one AC cycle. The second calculates losses by component by making use of Simscape™ logging. The small difference in calculated efficiency value is due to differences between trapezoidal integration used by the script and the greater accuracy achieved by the Simulink® variable-step solver.
