Abstract: This disclosure presents a power switching module combining a novel gate driver with a photonic isolated power source which can output a high voltage and high power at the same time, and thus can drive a power semiconductor device. The disclosed power switching module could simplify the switched mode power supply structure to (1) replace the isolated power supply module; (2) simplify circuitry of the gate driver by integrating gate driver signaling opto-electronics; and (3) provide a module with power semiconductor device under switched mode power supply structure.

Abstract: A sensor is provided for monitoring a mineral acid dissolved in a liquid. The sensor includes an internal reflection window which, in use, is in direct contact with the liquid. The sensor further includes a mid-infrared light source which directs a beam of mid-infrared radiation into said window for attenuated internal reflection at an interface between the window and the liquid. The sensor further includes a first narrow bandpass filter which preferentially transmits mid-infrared radiation over a band of wavelengths corresponding to an absorbance peak of the dissolved mineral acid to filter internally reflected mid-infrared radiation received from the window. The sensor further includes an infrared detector which detects filtered mid-infrared radiation transmitted through the first filter.
