I have a school project that implements a digital electronics power converter. It will be a current controller. The power source is also voltage controlled using a commercial power converter. The voltage controller switches at about 20 KHz. The current drawn from the power source must be sampled.
Is the LEM LAH 50-P current transducer able to satisfy the requirements? It has a step response time of under 500 ns (2MHz). If the voltage controller is switching at 20 KHz, can the current be sampled at 40 KHz?
Is the following the correct mode of operation? :
Place the sensor in series with the power line (breaking the line by connecting one end to the in terminals and the other to the out terminals). Then connecting 12 to 15 V to the Uc terminals.
