    Shunts for sensorless FOC

    This is my first time using the 2 shunt method of sensorless field oriented control (3 phase wye). Do I place the shunts between the source and ground for 2 of the 3 phases low side mosfets? Or do I place the shunts between where the high side and lowside mosfets connect to the winding? All...

    Bifilar Winding

    I've never used Bifilar Winding, and had a question regarding some conflicting information. This is for parallel bifilar winding where the current flows in the same direction in both wires. I've seen it said that bifilar winding 'multiplies' the inductive field. But that doesn't seem to...

    No devices in Precision RTL

    I'm new to PLC's, just finished writing and simulating my first verilog. But now I'm doing logic synthesis for the first time and running into an issue. Using Precision, I can't find any devices when I go to "Setup Design". It just says "No FPGA Devices" and doesn't even show the names of any...

    Driving dual switch PWM

    I'm pretty new to PWM design, and I haven't seen any examples of how to drive a dual switch PWM. Every example I've seen seems to only drive a single mosfet tied to ground. No matter what I do I can't seem to get the switches working, at least in the simulator. What I want is both...
