? Design, develop, and implement control algorithms and software for power electronics including rectifier, converter, and inverter circuits
? Perform Testing, verification, and troubleshooting of control algorithms and software on power conversion hardware
? Develop specifications and requirements of the control software related to the electrical characteristics of the power conversion equipment
? Document the algorithm and software development process within software tools
? Document laboratory testing process along with testing results in standalone written reports
? Develop and improve validation plans for evaluation of the control software within the power conversion equipment
? Integrate the control software with the other software functions of the power conversion equipment
? Stay informed on the latest theories, techniques and technical developments related to control systems

EDUCATION AND EXPERIENCE REQUIREMENTS
? BS Degree in Electrical Engineering from an ABET accredited school. (MS preferred)
? 3-5 years related experience in power electronics engineering applying control systems theory
? Skilled in control system theory and its applications including system modeling and simulation
? Strong hands-on troubleshooting skills at the control loop level and the power conversion equipment system level
? Solid understanding of advanced power electronics topologies
? Experience with pulse width modulation (PWM) schemes. sinusoidal PWM and space vector PWM
? Experience with power conditioning schemes. Nonlinear, unbalanced, harmonic compensation
? Proficient in power electronics modeling and simulation tools. (LTspice, MATLAB, Simulink, PSIM)
? Familiarity with TI DSPs
? Experience in developing control systems for MCU and DSPs in C programming language
? Understanding of communication protocols. (SPI, CAN, I2C, Modbus TCP/IP)
? Experience with software management systems and software version control tools. (GitHub or GitLab)
? Familiarity with test equipment such as oscilloscopes, digital multimeters, power analyzers, and spectrum analyzers
? Familiarity with low voltage distribution systems: single phase, split phase, and three phase up to 600VAC and frequencies from 50 to 800 Hz
