TL;DR: This paper presents a solution to improve the already mentioned drawbacks of ACHB inverters by using a high-frequency link using only one dc power source, which can be selected according to the application (regenerative, nonregeneration, and with variable or permanent voltage amplitude).

TL;DR: Simulations and experimental results show the feasibility to implement this “one-source” multilevel system, intended for application in EVs from power ratings up to 150 kW, based on a small and cheap high-frequency link.

TL;DR: RNAPol-ChIP advantageously compares with methods based on the analysis of steady-state mRNA (northern blot or RT-PCR), and informs on real-time transcription with results comparable to those of methods such as nuclear run-on or run-off, which require the isolation of highly purified nuclei.

TL;DR: The authors propose to improve any CM topology through two solutions: use optimal voltage asymmetries (ratios), higher than conventional ones; replace the voltage sources by floating capacitors balanced with a new control and/or a high-frequency link.

TL;DR: A nonredundant three-stage 27-level inverter using ldquoHrdquo converters is analyzed for medium- and high-power machine drive applications and the application of special pulsewidth modulation (PWM) strategies on the 27- level converter helps to keep positive average power at the medium power bridges and zero averagePower at the low-power bridges.
