NexGen Power Systems designs and manufactures gallium nitride (GaN) power transistors for the $4.8B high-voltage (1200 V) power transistor market. GaN makes transistors that are 10 times faster than silicon (Si) power devices enabling economically significant improvements in sophisticated power systems in their physical size, cost and efficiency. GaN offers a quantum leap over Si in power management performance and has significant cost, performance and reliability advantages. Applications for GaN transistors include server power supplies for Data Centers, Motor Drives, Electric Cars and Solar Inverters.
NexGen Power Systems is headquartered in Santa Clara, California. It builds the GaN power devices in a state-of-the-art fabrication facility located in Syracuse, New York.
Principal Applications Engineer
- The ideal candidate’s role is to develop high performance switching power supply demonstrations using new device technology and be able to communicate to the industry its salient features. This new device technology enables pushing up performance characteristics such as efficiency and switching frequency. Thus typical boundaries that stand in the current industry will be pushed to the limit.
- Develop high performance power supply demonstrations that are beyond the norm
- Write white papers, application notes, and/or articles about the power supplies and technology
- Attend industry conferences to talk about the technology
- Meet and talk with customers about the technology and its benefits
An ideal candidate should be an excellent team player and mentor to others while being capable of developing advanced power supplies, especially AC/DC power supplies. Such a candidate should be familiar with the typical design flow of a switching power supply. In addition, such a candidate should also be comfortable with modeling and designing the power supply and its critical components (i.e. controls, management, transformer, etc). Likewise, a candidate should be familiar with the typical testing requirements and methods of a power supply.
In summary, an excellent candidate should possess the following:
- Several years experience designing switching power supplies, preferably AC/DC
- Knowledge of topologies and tradeoffs between topologies
- Familiar with power supply testing and regulatory requirements
- Magnetics structures and design for switching power supplies
- Familiar with common analog and digital control techniques of switching power supplies
- Knowledge of switching device characteristics and their affect in switching power supplies
- Familiar modeling efficiency and losses of a switching power supply
- Good written and verbal skills
Additional desirable skills and/or knowledge:
- Familiar with general embedded design concepts
- Embedded programming in C
- Familiar with analysis tools and methods (i.e. Python-based scripting, MATLAB, etc)
- Knowledge of power applications in related fields (i.e. motors, inverters, etc)
