Micro-inverter for integrated grid-tie PV module using resonant controller
(2012-12-11)
Two-stage isolated converters for photovoltaic (PV) applications commonly employ a high-frequency transformer on the DC-DC side, submitting the DC-AC inverter switches to high voltages and forcing the use of IGBTs instead ...
High-Frequency Link: A Solution for Using Only One DC Source in Asymmetric Cascaded Multilevel Inverters
(IEEE, 2011)
Multilevel inverters are in state-of-the-art power conversion systems due to their improved voltage and current waveforms. Cascaded H-bridge (CHB) multilevel inverters have been considered as an alternative in the ...
3-D Space Vector PWM implementation for Four-Leg Voltage Source Inverter
(2011-12-28)
The Space Vector PWM implementation and operation for a Four-leg Voltage Source Inverter (VSI) is detailed and discussed in this paper. Although less common, four-leg VSIs are a viable solution for situations where neutral ...

Multilevel inverter, based on multi-stage connection of three-level converters scaled in power of three
(IEEE, 2002)
A multi-stage inverter using three-state converters is being analyzed for multipurpose applications, such as active power filters, static VAr compensators and machine drives for sinusoidal and trapezoidal current applications. ...
Position estimator and simplified current control strategy for brushless-DC motors, using DSP technology
(IEEE, 2003)
This paper describes a different way to sense the phase currents and to estimate DC rotor position of a brushless DC (BLDC) motor. For current control, the current is sensed taking the absolute value of two of the three ...
A high efficiency HPF-ZCS-PWM Sepic for electronic ballast with multiple tubular fluorescent lamps
(2002-01-01)
This paper presents a high efficiency Sepic rectifier for an electronic ballast application with multiple fluorescent lamps. The proposed Sepic rectifier is based on a Zero-Current-Switching (ZCS) Pulse-Width-Modulated ...
