PFCU-1500
1500W Single-Phase Power Factor Correction Converters
Description
Harmonic current distortion is a common power quality problem. Its adverse effects include
degradation of system voltage waveforms, reduction of power factor, etc. The 1500W single-phase
ac-dc converter with Power Factor Correction (PFC) is designed to reduce harmonic currents and
achieve near unity power factor in single-phase systems with frequency ranging from 45 Hz to 65Hz.
The 1500W PFC converter is composed of a rectifier bridge followed by a boost dc-dc converter
employing average current control.
Features
• Single-phase AC input, 85VAC ~ 265VAC input voltage, 45Hz ~ 65 Hz input frequency
• 395VDC output voltage
• Up to 1500W output power
• 50kHz switching frequency
• Near unity power factor
• Maximum 6% total harmonic current distortion at 220VAC, 1500W
• Over voltage, under voltage, over temperature protection, and instantaneous input current
protection.
• Base plate rated to 100 ^oC
