MATLAB: How to convert pwm_change_duty() function used in pic uC to a pwm code

electric_motor_controlpower_conversion_controlpower_electronics_controlpwm_change_duty() to matlab code

pwm_change_duty() is an already built in function used in pic microcontroller to change duty cycle. how do i convert it into a matlab formula.

Best Answer

function output = pwmoutput(tctnr,q,Tcntr)
% q - pwm duty assignment 0...1
% Tcntr - pwm counter period
% tau - pwm duty
% tcntr - current pwm counter condition 0...Tcntr
tau = q*Tcntr;
output = tcntr <= tau;

MATLAB: Pwm signal generation

f=1e3;a0=0;AmpSin=5; %sample wave values
t0=0;tf=0.01;Ts=1e-6; %time vector and resolution
v=0;AmpPwm=1; %Pwm options, increase v for lower dutty-cycle
t=t0:Ts:tf; %create the time vector
fun=AmpSin*sin(2*pi*f*t+a0); %create the function
pwm=AmpPwm*(fun>v); %get the pwm 
%plot it just to know if its working
clf
plot(t,fun)
hold on
plot(t,pwm,'r')
