This project created a Medium Frequency Power Control (MFPC) for industrial furnace applications. Powered by a high-capacity Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET)-based inverter under the control of an industrial microcontroller, the MFPC optimizes energy usage while providing precision in process control. The inverter takes 650 Volts from a rectifier and converts it to a stable 680 VAC at 1 kHz. A Raspberry Pi was utilized to control the MFPC, allowing RoMan Manufacturing to optimize industrial power management by utilizing MOSFETs, which have less losses than the insulated-gate bipolar transistors (IGBTs) that are currently on the market for electric furnaces.

Individuals without the use of a limb face significant challenges in interacting with their surroundings. These unique challenges are often remedied with the use of a prosthetic limb. However, prosthetics provide limited movement options, lack natural neural control from the user, and require specific maintenance guidelines. To improve this solution, a Senior Design team at Western Michigan University has proposed the development of a robotic arm that is controlled by brain signals received by an electroencephalogram (EEG) cap worn by the user. This project aims to be completed as a proof of concept for EEG controlled prosthetic limbs.

To make this process automatic, separate detection and alert modules have been designed and built to detect nearby obstacles. Camera and distance sensor data feed a machine-learning model to infer the presence of an obstacle. The obstacle classification is sent over Bluetooth to trigger vibrations on the back of the user’s hand.

Dedicated systems that transmit analog data around a machine can add cost to the machine’s construction, so a more cost-effective device is needed to move these signals. By making use of the local controller area network (CAN) bus on the machine, a microcontroller was programmed to convert the analog information to digital before packaging the information in the J1939 format for heavy-duty vehicles. That packaged information is then broadcasted every 100ms onto the CAN bus. The microcontroller and other contributing components are mounted to a prototype PCB that transmits the information reliably at a cheaper price than the current system.

Electric vehicles require compact and efficient motors to compete with fossil-fueled alternatives. In-wheel motors are an attractive alternative to conventional electric motors due to their compact form factor. The nature of these motors makes it challenging to implement sensor-based field-oriented control. The goal is to develop a position-sensor system compatible with in-wheel motors and adapt a field-oriented control program to utilize the sensor inputs. This enables the in-wheel motor to operate at a higher efficiency than what is currently available on the market.

Maximum Power Point Tracking (MPPT) is a process that tracks the maximum output power of a solar panel (PV) to optimize usable solar energy efficiency. The MPPT solar charge controller sits between a 12V 20W solar panel and a 12V battery (load). The solar charge controller is operated by an Arduino microcontroller utilizing MPPT algorithms to measure and track PV output voltage and current levels. These levels supply the input to a DC-DC converter, which maintains desired output voltage or current levels for the load. Different MPPT algorithms can be selected within the charge controller to test changes in MPPT efficiency.

Two Phase Inverter Design

Nanogyro has designed a pair of coils that are 90° out of phase and the coils are to be driven by two AC voltages that are also 90° out of phase. Nanogryo has been using a signal generator to produce the two AC voltages, but as the signal’s frequency changes, the output impedance also changes, which is a problem. A microcontroller will be used to produce sine waves at the appropriate frequencies and constant phase output. The digital processing will remove any analog factors affecting the phase of the signals. This project will use a DC voltage to generate the two AC voltages (90° out of phase) with constant output impedances as the frequency changes.
