Learn about a simple way to measure total load current using just one op amp.

Figure 1: IGBT & Diode Mounted on Lead Frame of a TO-247 Package Power Calculations The voltage and current waveforms must be multiplied and then integrated to measure the power. Although the simple ...

It was based on a constant current source that is controlled by a DAC hooked up to the Arduino. By measuring both the resulting voltage and current of the load, the system can dynamically adapt to ...

In his video [Afroman] describes how the LM317 can be used to regulate current rather than voltage to provide a constant current source under varying load.
