| SENSITRON SEMICONDUCTOR TECHNICAL DATA DATA SHEET 5112 REV. - PFCU-3000 3000W 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 3000W 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 3000W PFC converter is composed of a rectifier bridge followed by a boost dc-dc converter employing average current control.

Note: PFCU-3000 1) When the output power is below 10% of the rated power, the input current will be significantly distorted. However, the output voltage remains in regulation. 2) Not tested on actual units. Ensured by design. PIN Description SYMBOL N, L DC+, DCL_EN ON COM 12V TEMP AC line inputs DC outputs Load enable pin. Open collector output with an internal 100 ohm resistor. Maximum collector current is 100mA. When Vo is lower than 365V, L_EN is shorted to "COM". PFC enable pin. When "ON" pin is connected to COM, PFC is enabled. Otherwise, PFC is disabled and Vo is the rectified AC input voltage. Control Signal Reference. Connected to "DC-"internally. Bias Voltage Supply. Output current up to 20mA. Substrate temperature sensor output. 10mV/ Kelvin Or (TEMP x 100 - 273 ) oC DESCRIPTION TYPICAL APPLICATION L EMI AC Line Filter N L_EN DC+ PFC DC- Load Figure 2. Typical application of 3000W single-phase PFC converter Figure 2 illustrates the configuration of 3000W single-phase PFC converter in a typical application. External capacitor filter is required at the PFC converter output. Selection of the output capacitor is usually determined by the switching frequency ripple current, the second harmonic ripple current, the DC voltage, the output ripple voltage and the hold-up time. All electrical characteristics in this datasheet are tested with an output capacitor of 1400F, which generates maximum 20V peak-peak 2nd harmonic ripple voltage. The inrush current is limited by an internal 15 ohm surge resistor. To reduce power loss, the resistor is shorted after the PFC is powered up for 350m sec, no matter if the PFC converter is enabled. Having a heavy load connected to the PFC output during start-up time will delay the charge of the output capacitor, and may result in high input current spikes. If customer load does not have under voltage lockout, it is recommended to insert a switch (e.g. a relay), controlled by the pin "L_EN", between the load and the output capacitor, as shown in Figure 2. "L_EN" changes its status when the output voltage reaches 365VDC. The logic of "L_EN" is configurable. * 221 WEST INDUSTRY COURT * DEER PARK, NY 11729-4681 * PHONE (631) 586-7600 * FAX (631) 242-9798 * * World Wide Web Site - http://www.sensitron.com * E-mail Address - sales@sensitron.com * SENSITRON SEMICONDUCTOR TECHNICAL DATA DATA SHEET 5112 REV. - PFCU-3000 MECHANICAL OUTLINE * 221 WEST INDUSTRY COURT * DEER PARK, NY 11729-4681 * PHONE (631) 586-7600 * FAX (631) 242-9798 * * World Wide Web Site - http://www.sensitron.com * E-mail Address - sales@sensitron.com * SENSITRON SEMICONDUCTOR TECHNICAL DATA DATA SHEET 5112 REV. - PFCU-3000 DISCLAIMER: 1- The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
