Abstract: Examples of the disclosure relate to systems and methods for reducing EMI in electrical systems. The electrical system can include a DC power source and a load component to receive direct-current (DC) electrical energy from the DC power source through a DC bus. The system also includes a filter network coupled to the DC bus between the DC power source and the load component to suppress electromagnetic interference (EMI) on the DC bus. The filter network includes a first capacitor and at least a second capacitor conductively coupled in series with one another between the positive voltage line and the ground line of the DC bus. Additionally, the capacitance of the first capacitor is different from the capacitance of the second capacitor. The capacitance values of the two capacitors are selected to provide a desired performance characteristic for suppressing EMI.

Abstract: Examples of the present disclosure relate to a device, method, and medium storing instructions for execution by a processor for estimating motor winding temperature. In an example, a device for estimating motor winding temperature includes a motor shaft and a motor winding. The device may include a current sense resistor to detect the current passing through a common wiring. The device may include a digital to analog converter to convert an input voltage to an analog signal for comparison to the voltage and to generate a differential voltage using the signals received from the current sense resistor and an initial voltage supplied to the motor winding. The device may include a processor to use the differential voltage and a current input value to calculate a resistance of the motor winding from comparison to a temperature conversion curve.
