H8 Inverter for Common-Mode Voltage Reduction in Electric Drives [PDF]
IEEE Transactions on Industry Applications, 2016 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 ...

Phase detector for three-phase power factor controller [PDF]
, 1984 A phase detector for the three phase power factor controller (PFC) is described. The phase detector for each phase includes an operational amplifier which senses the current phase angle for that phase by sensing the voltage across the phase thyristor ...

An active circuit for cancellation of common-mode voltage generated by a PWM inverter [PDF]
, 1997 This paper proposes an “active common-noise canceler (ACC)” that is capable of eliminating the common-mode voltage produced by a PWM inverter. An emitter follower using complementary transistors and a common-mode transformer are incorporated into the ACC,

Pediatric Blood &Cancer, EarlyView.ABSTRACT Surveillance imaging aims to detect tumour relapse before symptoms develop, but it's unclear whether earlier detection of relapse leads to better outcomes in children and young people (CYP) with medulloblastoma and ependymoma. This systematic review aims to identify relevant literature to determine the efficacy of surveillance magnetic ...

Common-Mode Voltage Reduction of Three-Level Four-Leg PWM Converter [PDF]
IEEE Transactions on Industry Applications, 2014 This paper presents a carrier-based pulsewidth modulation (PWM) method that reduces the common-mode voltage (CMV) of a three-level four-leg converter. Based on an analysis of space vector PWM (SVPWM) and sinusoidal-PWM switching patterns, the fourth-leg pole voltage of a three-phase converter, known as the “f pole voltage,” is manipulated to reduce the
