    Control for a 3kW Thermal Resistance

    I'm thinking in something like the block diagram in the image, but I have issues about the way the PWM is going to use the phase obtained by the transformer, how do I take the phase into consideration in an op-amp circuit? There's also the consideration of the Vref coming from the FieldPoint and...

    Control for a 3kW Thermal Resistance

    Thanks! I've got my welcome when I saw some really good topics around......... About the 6.6V, well, they are outputs of a National Instruments tool, FieldPoint, which you can vary from LabView from 0 to 6.67V, and that's why I want a mechanism to control with 0V-0W and 6.67V-3kW or something...

    Control for a 3kW Thermal Resistance

    I didn't give full details, the main supply voltage comes from a 220V line, and the resistance is of 16.1Ohms with a current of 13.6A.

    Control for a 3kW Thermal Resistance

    Hi, guys, I just find this page, and is an amazing one.  ;D I've got a problem with this kind of circuit, I'm thinking a dimmer could solve the problem, just one thing, I need to control the power from 0-100% with one voltage input of 6.67V max, so I want to know your opinion, if you think that...
