This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V.

Also, because the PPTC element is in series with the MOV, no additional overcurrent protection is required, which helps reduce component count and optimize board space. Figures 2 and 3 below show how ...

Penetration of the power grid by renewable energy sources, distributed storage, and distributed generators is becoming more widespread. Increased utilization of these distributed energy resources ...
