pwm heater regulator feedback
Thanks a lot. By the way, the system is a Real-Time PC Based Multipurpose Heat Pump used to dry products like fruits, vegetables, ceramic materials, etc. At the back of the heating element is a fan that pushes the hot air into the rectangular tube. At the center...
ac power control with pwm
Yes there is a 2°C step on the ADC 0808 part but we used op-amp to double the output voltage from 10mv to 20mv to make it 1°C per step.
We used the optoisolator MOC3041, is this a non-zero crossing kind?
What is a thermal inertia? We did not consider this...
pwm heater controller
The feedback controller is also controlled by the paralel port. The circuit of the feedback is composed of three temperature sensors LM35DZ interfaced through an ADC0808 with 20mv per step. Then the ADC is then connected to a 74LS244 to be connected to the parallel port...
pwm heater
The machine that we are designing is controlled by a Visual Basic program. The main goal of the machine is to achieve the graph of the Temperature over time according to the Ramping rate inputted by the user.
The graph of the ramping rate is linear while the graph of the...
