Low level modular multilevel converter (MMC) is a promising candidate for medium voltage applications such as MVDC (medium DC current) transmission and megawatt machine drives. Unlike high-level MMC using nearest modulation (NLM), the low-level pulse width (PWM) or NLM + PWM affected by common mode (CMV) due to frequent change of switching state. This CMV causes electromagnetic interference (EM...

This paper focuses on a differential voltage measurement in low-voltage automotive devices whose subunits are separated with low-side safety switch. In contrast to conventional applications high-side switches, common-mode (CMV) negative polarity exists at the input of signal conditioning circuitry. To overcome shortage dedicated integrated circuits capable withstanding CMV, investigates single-...

This paper proposes a pulsed power generator which consists of two types of switched-capacitor booster modules. A doubling mode module employed to elevate the input voltage to a specified level and, constant mode module is used to increase the elevated voltage into the finally intended bipolar output voltage. Also, the proposed modular structure does not utilize any switches across the load. Ot...

The common mode voltage (CMV) causes many issues and negatively affects the performance of power system in a hybrid electric vehicle HEV. Therefore, this paper suggests simple method for mitigating CMV two level three phase source inverter VSI with RL load. Hence, technique chosen purpose is based on model predictive control. Otherwise, when compared to standard method, can successfully mitigat...
