Active cancellation of the common‐mode voltage produced by a voltage‐source PWM inverter
This paper proposes an “active common-mode noise canceler” that is capable of eliminating the common-mode voltage produced by a voltage-source PWM inverter. It generates a compensating voltage which has the same amplitude as, but the opposite phase to, the common-mode voltage produced by the PWM inverter. The compensating voltage is superimposed on the

Ultra-low voltage common-mode voltage detector circuit
A new common-mode voltage detector circuit to be used in the common-mode feedback loop of ultra-low voltage fully differential amplifiers is presented. The proposed circuit behaves linearly for most of the signal range and is able to operate with supply voltages as low as 0.4 V.

H8 Inverter for Common-Mode Voltage Reduction in Electric Drives [PDF]
This paper presents a modified two-level three-phase inverter for the reduction of the leakage current. With respect to a traditional two-level inverter, the proposed solution reduces the common-mode voltage (CMV), both in amplitude and frequency. Between the dc source and the traditional three-phase bridge, two active dc-decoupling devices and a ...
