چکیده
This letter proposes a control strategy for reducing ripple current in DC-link capacitor of single-phase uninterruptible power supplies (UPS). The proposed method aims to reduce the by difference between input and output instantaneous power. waveform should satisfy harmonic regulation be as close possible load current. Therefore, an auxiliary buck chopper was added compensate capacitor. Experimental result confirm that reduces RMS value 27.9%.

A Compact Topology for Single-Phase Line-Interactive UPS Using Small DC-Link Capacitor
A novel pulse-width modulated (PWM) single-phase line-interactive uninterruptible power supply (UPS) based on the small dc bus capacitor is presented. The proposed system is made up of an ac chopper which includes a diode rectifier, a boost switch, a charger and an inverter. It has the features of a small dc bus capacitor, small input and output inductors, and low switching loss, and is very su...
متن کاملDCM Frequency Control Algorithm for Multi-Phase DC-DC Boost Converters for Input Current Ripple Reduction
In this paper, a discontinuous conduction mode (DCM) frequency control algorithm is proposed to reduce the input current ripple of a multi-phase interleaved boost converter. Unlike conventional variable duty and constant frequency control, the proposed algorithm controls the switching frequency to regulate the output voltage. By fixing the duty ratio at 1/N in the N-phase interleaved boost conv...
متن کاملA simplified control strategy for single-phase UPS inverters
Though there are many strategies to control single-phase uninterruptible power supply (UPS) inverters, they suffer from some drawbacks, the main being complexity. This paper proposes a simple dual-loop controller for the single-phase UPS inverter with the LC filter. The suggested control scheme uses the capacitor current as the feedback signal in the inner current loop. No fictitious phase gene...

15 صفحه اولAnalysis of Input Current Ripple and Optimum Filter Capacitor for Fuel-Cell-Based Single-Phase Inverter
Most single-phase inverters, being sourced by fuel cell stacks (FCSs), subject the stacks to reflected low-frequency (120 Hz) current ripples that ride on average dc currents. The ripple current impacts the sizing and efficiency of the FCS. As such and typically, a passive or active filter is required at the input of the inverter (or output of the FCS) to mitigate the ripple current. Toward tha...
