It is my utmost pleasure to welcome you to the 2016 IEEE Applied Power Electronics Conference and Exposition (APEC 2016), at the Long Beach Convention Center, in Long Beach, California.
lists the year, site, dates, General Chair and Program Chair for all IEEE Applied Power Electronics Conference and Exposition (APEC) meetings 1986-2015.
APEC 2017 continues the long-standing tradition of addressing issues of immediate and long-term interest to the practicing power electronic engineer. Outstanding technical content is provided at one of the lowest registration costs of any IEEE conference. APEC 2017 will provide a) the best power electronics exposition, b) professional development courses taught by world-class experts, c) presentations...
A recently proposed third harmonic injection rectifier (two half-bridge legs) - serving as optional solution for passive three-phase diode bridge systems with LC output filter - is characterized by unity power factor (λ ≈ 1) and low harmonic input currents (THD < 5%). The rectifier at hand, furthermore sticks out of the crowd due to a very low number of active and passive switches compared to similar...
This paper proposes a simplified vector control method with output capacitor voltage balance for voltage oriented control of the three-level three-switch Vienna rectifier. The proposed control method makes use of a single carrier based pulse width modulated (PWM) switching technique instead of complex space vector method for the Vienna rectifier. The vector control method is comprehensively compared...
This paper presents a neutral point deviation compensating control algorithm applied to a 3-level NPC converter. The neutral point deviation is analyzed with a focus on the current flowing out of or into the neutral point of the dc-link. Based on the zero sequence components of the reference voltages, this paper analyzes the neutral point deviation and balancing control for 3-level NPC converter....
This paper deals with a modular, isolated-output, polyphase, AC/DC converter based on the use of Resistor Emulators (REs). A RE is a DC/DC converter that behaves as a resistor at its input port. The value of this resistor (input impedance) is controlled by the converter duty cycle. In the proposed topology, all the REs are controlled to have the same input impedance, whose value is determined by the...
In this paper a PWM method for zero voltage switched three-phase isolated rectifier is presented. The presented PWM scheme features lower maximum output inductor current ripple and lower duty-cycle loss by more than half. Therefore, a smaller output inductor can be used and the ZVS operation can be extended at wider load range for MOSFET devices by increasing the leakage inductance of the transformer...
In this paper, a control method for three single-phase isolated ac-dc converter modules employed to implement an isolated three-phase, three-wire ac-dc converter is presented and its detailed design procedure provided. In the described control the input voltages of the Y-connected single-phase modules with floating common Y point are kept within a safe range by equalizing their input admittances....
Three-phase isolated ac-dc converters can be implemented either with a direct three-phase PFC rectifier front end followed by an isolated dc-dc converter, or with three single-phase isolated ac-dc converters. Generally, the major advantage of the modular implementation with three single-phase converters is its ease of power expandability. In implementations with Y-connected single-phase modules in...
Advances in power electronics are enabling More Electric Aircrafts (MEAs) to replace pneumatic systems with electrical systems. Active power factor correction (PFC) rectifiers are used in MEAs to rectify the output voltage of the three-phase AC-DC boost converter, while maintaining a unity input power factor. Many existing control strategies implement PI compensators, with slow response times, in...
This paper proposes a single-stage three-phase rectifier with high-frequency isolation, power factor correction, and bidirectional power flow. The presented topology is adequate for dc grids (or smart-grids), telecommunications (telecom) power supplies, and more recent applications such as electric vehicles. The converter is based on the three-phase version of the dual active bridge (DAB) associated...
This paper presents the first monolithically integrated two-phase series capacitor buck converter. This converter achieves over 60 A/cm3 current density. The series capacitor buck converter topology enables high frequency (HF) operation up to 5 MHz per phase without special magnetics or compound semiconductors. An adaptive constant on-time controller provides fast load transient response and fixed...
