Safety On The Bench: Hazards And Precautions In The Power Electronics Lab

Focus:

This article offers an introduction to the topic of electrical safety in the power electronics laboratory to help engineers understand the possible hazards that are present and the possible safety measures that may be implemented. It frames the discussion in terms of work on four different power electronics applications involving progressively higher energy levels—a 100-W offline converter; a high-current, low-voltage application; a 20-kW inverter; and power converters for electric vehicles. The author puts the different energy levels present in these applications in perspective, describes the different hazards they pose, and a range of protective measures. This article is not intended to be a complete work or a substitute for any OSHA, local, corporate or national training and safety guidelines.

What you’ll learn:

• How to understand the range of safety hazards present in the power electronics development lab and possible safety measures to address them (overview)
