In recent year, common mode voltage (CMV) elimination methods are considered to improve the reliability of three-level quasi-switched boost T-type inverter (TL-qSBT2I). The space-vector modulation method (SVM) can control operation eliminate CMV. proposed applies medium vectors and zero vector synthesize reference CMV while output is unchanged compared SinPWM technique. order prevent active fro...

In this paper is presented a novel constant transconductance CMOS differential amplifier. The circuit uses a modified CMOS inverter to process polarisation currents of the complementary differential amplifier in order to maintain constant transconductance over the entire common-mode input voltage range. Simulation shows error less than ±6.12 % for a single supply voltage of 1.5 V. Key-Words: lo...

Neutral point voltage control converters (NPVCC) are being considered for AC drive applications, where their additional degree of freedom can be used different purposes, such as fault tolerance or common mode (CMV) reduction. For every PWM-driven converter, the CMV is an issue that must since it lead to shaft voltages between rotor and stator windings, generating bearing currents accelerate deg...

This paper presents a novel CMOS differential voltage current conveyor based on a wide linear range transconductor with common mode detection. The differential voltage current conveyor exhibits a wide dynamic input range of ±0.9V. It is used to realize an instrumentation amplifier, a multiple input single output filter, and a single input multiple output universal filter. PSPICE simulations of ...

A modular multilevel converter (MMC) can generate different common-mode voltage (CMV) values due to the high-frequency changing of switching state under various modulation strategies. The dv/dt will produce current in equivalent loop ground, which affect insulation and shorten life equipment. To eliminate effect on MMC operation, a elimination strategy (0CMV-SVPWM) is proposed for five-level sp...
