   There is a rising need for rapid and reliable analytical methods for separating microorganisms in clinical and biomedical applications. Microscale-insulator-based electrokinetic (iEK) systems have proven to be robust platforms for assessing a wide variety of microorganisms. Traditionally, iEK systems are usually stimulated with direct-current (DC) potentials. This work presents a comparison between using DC potentials and using DC-biased alternating-current (AC) potentials in iEK systems for the separation of microorganisms. The present study, which includes mathematical modeling and experimentation, compares the separation of bacterial and yeast cells in two distinct modes by using DC and DC-biased AC potentials. The quality of both separations, assessed in terms of separation resolution (Rs), showed a complete separation (Rs = 1.51) with the application of a DC-biased low-frequency AC signal but an incomplete separation (Rs = 0.55) with the application of an RMS-equivalent DC signal. Good reproducibility between experimental repetitions (<10%) was obtained, and good agreement (~18% deviation) was observed between modeling and experimental retention times. The present study demonstrates the potential of extending the limits of iEK systems by employing DC-biased AC potentials to perform discriminatory separations of microorganisms that are difficult to separate with the application of DC potentials.

5. Comparative Analysis of the Dual-Path Hybrid Switched-Capacitor DC-DC Converter and the 3-Level Buck Converter

   Dual-Path (DP) DC-DC converters have been proposed as an alternative to traditional hybrid switched capacitor (SC) converters that can operate with a smaller, lower-quality, or higher effective series-resistance ESR inductor. The dual-path approach uses a partially hard-switched flying capacitor to reduce DC inductor current and associated resistive conduction losses. However, the SC hard-charging losses and higher inductor current ripple can partially or completely offset the advantage of reduced inductor DC current depending on the operating conditions and component parameters. In this work, we develop a unified model for all four 2:1 SC-based DP converters that captures SC hard-charging loss and inductor conduction loss as a function of conversion ratio, switching frequency, flying capacitance, and inductor ESR with fixed-volume inductor scaling. While there are regimes where the DP approach has advantages, there are also many scenarios where the traditional hybrid approach outperforms the respective dual-path alternative.
