NCP1653EVB 300 W, Wide Mains, PFC Stage Driven by the NCP1653 Evaluation BoardUser's Manual http://onsemi.com EVAL BOARD USER’S MANUAL Introduction The NCP1653 is a Power Factor Controller to efficiently drive Continuous Conduction Mode (CCM) step-up pre-converters. As shown by the ON Semiconductor application note AND8184/D, that details the four key steps to design a NCP1653 driven PFC stage, this circuit represents a major leap towards compactness and ease of implementation. Housed in a DIP8 or SO−8 package, the circuit minimizes the external components count without sacrificing performance and flexibility. In particular, the NCP1653 integrates all the key protections to build robust PFC stages like an effective input power runaway clamping circuitry. When needed or wished, the NCP1653 also allows operation in Follower Boost mode* to drastically lower the pre-converter size and cost, in a straight-forward manner. For more information on this device, please refer to the ON Semiconductor data sheet NCP1653/D. The board illustrates the circuit capability to effectively drive a high power, universal line application. More specifically, it is designed to meet the following specifications: • Maximum output power: 300 W • Input voltage range: from 90 Vrms to 265 Vrms • Regulation output voltage: 385 V • Switching frequency: 100 kHz This application was tested using a resistive load. As in many applications, the PFC controller is fed by an output of the downstream converter, there is generally no need for an auto-supply circuitry. Hence, in our demo-board, the NCP1653 VCC is to be supplied by a 15 V external power supply. The external voltage source that is to be applied to the NCP1653 VCC, should exceed 13.25 V typically, to allow the circuit startup. After startup, the VCC operating range is from 9.5 to 18 V. The voltage applied to the NCP1653 VCC must NOT exceed 18 V. The NCP1653 is a continuous conduction mode and fixed frequency controller (100 kHz). The coil (600 mH) is selected to limit the peak-to-peak current ripple in the range of 30% at the sinusoid top, in full load and low line conditions. Again, for details on how the application is designed, please refer to the ON Semiconductor application note AND8184/D. As detailed in the document, the board yields very nice Power Factor ratios and effectively limits the Total Harmonic Distortion (THD). *The “Follower Boost” mode makes the pre-converter output voltage stabilize at a level that varies linearly versus the AC line amplitude. This technique aims at reducing the difference between the output and input voltages to optimize the boost efficiency and minimize the cost of the PFC stage (refer to MC33260 and NCP1653 data sheet at www.onsemi.com). © Semiconductor Components Industries, LLC, 2012 September, 2012 − Rev. 1 1 Publication Order Number: EVBUM2139/D NCP1653EVB Figure 1. The Board For the sake of consistency, this evaluation board reports the performance and results that were obtained using the CoilCraft coil. However, it has been checked that the two other coils yield high performance too. Three coils from three different vendors have been validated on this board: • C1062−B from CoilCraft • MB09008 from microSpire • SRW42EC−E02H001 from TDK http://onsemi.com 2 L Figure 2.

THD vs. Pin Figure 8. Efficiency vs. Pin The Total Harmonic Distortion keeps below 10% from Pmax (maximum power – 300 W) down to about Pmax/5. The efficiency remains higher than 90% for input powers ranging from 67 to 330 W. In standby (no load conditions), the PFC stage enters a stable burst mode, where the circuit keeps regulating the output voltage and minimizes the power consumption (See Figure 11). http://onsemi.com 6 NCP1653EVB Table 2.

The Total Harmonic Distortion keeps below 15% from Pmax (maximum power – 300 W) down to about Pmax/5. Again the efficiency keeps high in a large power range. More specifically, it remains higher than 91% for input powers ranging from 67 to 330 W. In standby (no load conditions), the PFC stage enters a stable burst mode, where the circuit keeps regulating the output voltage and minimizes the power consumption. http://onsemi.com 7 NCP1653EVB Thermal Measurements Measurements Conditions: • • • • • • The following results were obtained using a thermal camera, after a 1 h operation at 25°C ambient temperature. These data are indicative. They show that the demo-board may require additional heatsink capability if used in high ambient temperature applications. Vac = 90 V Pin = 326 W Vout = 365 V Iout = 0.82 A PF = 0.999 THD = 3% Coil Coil Power MOSFET Heatsink Bulk Capacitor Output Diode (ferrite) (wires) Input Bridge 100°C 80°C 50°C 75°C 100°C 130°C 85°C No Load Operation Iin: ac line current (CH3 – 10 A/div) 388V Vout (CH3) Vin (CH2) Vpin5 (CH1) Figure 11. Pout = 0 W, Vac = 230 V When in light load, the circuit enters a welcome burst mode that enables the circuit to keep regulating. Vpin5 oscillates around the pin5 internal reference voltage (2.5 V). The power losses @ 220 Vac, are nearly 130 mW. This result was obtained by using a W.h meter (measure duration: 1 h). http://onsemi.com 8 NCP1653EVB Soft-Start The NCP1653 grounds the “Vcontrol” capacitor when it is off, i.e., before each circuit active sequence (“Vcontrol” being the regulation block output). Provided the low regulation bandwidth required by PFC stages, “Vcontrol” increases slowly. As a result, the power delivery rises gradually and the PFC pre-regulator startup smoothly and noiselessly. DRV (Vpin7) Vpin2 (CH3) (Vcontrol – regulation output) Vout (CH1) Vin (CH2) Figure 12. http://onsemi.com 9 NCP1653EVB Test Procedure 1. Apply a 500 W/400 W resistive load across the output (between the “+VOUT” and “−VOUT” terminals of the board). 2. Adjust a 350 W or more, isolated ac power source so that it outputs a 110 VRMS, sinusoidal voltage (50 or 60 Hz). 3. Place a power analyzer able to measure: • The power delivered by the power source (“Pin”) • The power factor (“PF”) and the Total Harmonic Distortion (“THD”) of the current absorbed from the ac power source 4. Plug the application to the ac power source. 5. Supply the controller by applying 15 V to the VCC socket (between the “+12 V” and “GND” terminals of the board) and measure: Parameters Comments Limits VOUT Voltage Measured between “+VOUT” and “−VOUT” 365 V < VOUT < 385 V PF Power Factor > 0.990 THD Total Harmonic Distortion < 8% Efficiency 7. Gradually decrease the power source input voltage until the input current top becomes flat. Measure the plateau (see Figure 14). It must be between 4.9 and 5.3 A (over-current limitation). This test must be very short to avoid any excessive heating of the board. Immediately stop the test if the input current exceeds 5.3 A, or if the input voltage is below 75 VRMS). 8. Increase the ac power source voltage to 220 V and measure: Parameters Comments Limits VOUT Voltage Measured between “+VOUT” and “−VOUT” 375 V < VOUT < 395 V PF Power Factor > 0.980 THD Total Harmonic Distortion < 12% Efficiency > 93% 9. Observe the output voltage (i.e., the voltage between the “+VOUT” and “−VOUT” terminals of the board) with an oscilloscope. Unplug the PFC stage from the power source. Set the triggering level at about 200 V, the trigger position being set at 10% of the screen. Program the scope to observe 50 or 100 ms in single acquisition mode. 10. Abruptly apply the power source. Check that the output voltage keeps below 450 V (Over-Voltage Protection) (see Figure 15). > 91% 6. Observe the input current (current drawn from the ac power source) using a current probe and the oscilloscope. The current is nearly sinusoidal.
