Hi, I’m Brett an electrical engineer with a passion for tinkering and solving problems. Scroll down to explore some of the projects I’ve worked on in my spare time and learn more about me.
Check out some of my personal electronics projects below.
Grid Connected Inverter Simulation
Most use cases of automotive electrification revolve around grid to vehicle applications. This power transfer scheme involves a charger which is connected to the grid providing High Voltage DC to a vehicle.
The following page describes a MATLAB-SIMULINK model of an inverter synced with a utility grid’s fundamental frequency of 60 Hz that I created. Typical applications of this technology include emergency short term residential power, secondary power from nontraditional sources such as automobiles, and grid power factor stability.
In many industrial applications electrical motors are used to move product. Rather than just turning the motor fully on or off a variable frequency drive is used diversify the torque/speed profiles in accordance with the intended load.
This type of drive allows for precise control of a motor by modulating its frequency instead of the motor operating at a fixed frequency. VFDs allow for decreased stress on the motor due to slowed start/stop commands.
Power Protection and Supply Circuit Design
A vital skill as an EE is the ability to protect circuits from unwanted transients and electrical over stress. These occurrences of electrical overstress can be initiated by a plethora of different stimuli including reverse polarity connections, short circuits, exposure to lighting, and more.
The following page will show a circuit that protects the power input from the following:
→ Reverse Voltage
→ Over Voltage/Current: Including ESD and Transients
