Analysis and design of constant-frequency peak-current-controlled high-power-factor boost rectifier with slope compensation
This paper presents the analysis and the design of a peak-current-controlled high-power-factor boost rectifier, with slope compensation, operating at constant frequency. The input current shaping is achieved, with continuous ...
Trolleybus power system for operation with AC or DC distribution networks
This paper presents the development and experimental analysis of a special input stage converter for a Trolleybus type vehicle allowing its operation in AC (two wires, single-phase) or DC distribution networks. The ...
A HPF AC-AC converter for Permanent Magnet Generator applications
This paper describes the design and development of a high input power-factor (HPF) AC to AC converter for naval applications using Permanent Magnet Generator (PMG). The proposed converter comprises an isolated three-phase ...
Bridgeless interleaved boost PFC converter with variable duty cycle control
This paper proposes a bridgeless boost interleaved PFC (power factor correction) converter with variable duty cycle control. The application of bridgeless technique causes reduction of conduction losses, while the interleaving ...
Variable speed refrigeration system with HPF input rectifier stage
This paper is based on the analysis and implementation of a new drive system applied to refrigeration systems, complying with the restrictions imposed by the IEC standards (Harmonic/Flicker/EMI-Electromagnetic Interference ...
Conversor CA-CA de elevado fator de potência para aplicações com geradores de Ímã permanente
This paper proposes and describes a high power factor AC-AC converter for naval applications using Permanent Magnet Generator (PMG). The three-phase output voltages of the PMG vary from 260 Vrms (220 Hz) to 380 Vrms (360 ...
