```matlab
%% SVPWM Three-Phase Inverter Simulation
% This Simulink model simulates a three-phase inverter using SVPWM (Space Vector Pulse Width Modulation) technique.
%% Parameters
% Define the parameters of the system.
Vdc = 100; % DC voltage
f = 50; % Supply frequency
L = 10e-3; % Inductance
R = 10; % Resistance
C = 1e-6; % Capacitance
Vref = 50; % Reference voltage
theta_ref = 0; % Reference angle
%% Simulation
% Run the simulation and plot the results.

在该文件中,我们定义了一些参数,例如输入电压、频率、电感、电阻、电容等,并在模拟器中运行了SVPWM三相整流器。最后,我们绘制了输出电压、输出电流和转子角度,并将其显示在不同的子图中。
