AC-DC efficiency measurements need to include power factor

AC-DC efficiency measurements need to include power factor
Power converter designers compete to minimise losses, chasing the last decimal points of efficiency, η, the ratio of output to input power. But when it comes to calculating efficiency in AC-DC power supplies mistakes are often made as a result of omitting or improperly measuring power factor, which is why it is important for designers to understand power factor basics and how to incorporate it.

Designing with Peltier modules for precision thermal management

Designing with Peltier modules for precision thermal management
Sometimes cooling needs to be more tightly controlled than a simple heat sink and fan can manage. Rapidly fluctuating loads can make it hard to keep a component at a stable and cool temperature. However, this can often be important when trying to improve signal-to-noise performance or prevent damage to a system. By Bruce Rose, Principal Applications Engineer at CUI Inc.
