1 Fairchild Reference Design RD-549 This reference design supports inclusion of 2-phase interleave BCM PFC controller FAN96, 2-phase interleave CCM PFC controller FAN9672, and Fairchild Integrated Power Switch FSL336LRN; in a design of a Power-Factor-Correction (PFC) front-end up to 3 KW. This document should be used in conjunction with the FAN96, FAN9672 and FSL336LR datasheets as well as Fairchild s application notes and technical support team. Please visit Fairchild s website at:. Application Fairchild Device Input Voltage Range Maximum Power Output Condition Topology PFC Front-end with Auxiliary Power FAN96 FAN9672 FSL336LR V AC 3000 W 400 V DC 2 Phase Interleaved Boost PFC, HV Buck. General Description This reference design is made for a high efficiency, high power PFC up to 3 KW. It can be used in applications such as inverter type air conditioner, welding machine, EV charger, UPS etc. To achieve higher efficiency and power density, we adopted a twochannel interleave topology. To make the solution more flexible, we provided two control methods: Continuous Conduction Mode (CCM) and Boundary Conduction Mode (BCM) for options. Selecting the control mode is easily done by changing the two different daughter boards. Each control mode has its advantages and disadvantages, which are explained in the following description and test results. To adopt the IGBT as the switching device, we placed a frequency up limit circuit on the BCM control board. It can be disabled while using the MOSFET as the switching device. A buck mode auxiliary power was applied since no insulation is required on the PFC stage, and because the Buck converter is simple and cheaper than the flyback converter. Key Features for System Two phase/channel interleaved boost topology to achieve high efficiency and low current ripple. Inductors on board reduces system size. Auxiliary power built in. Plug and Play evaluation. Temperature monitoring heat sink fan control. Decreased standby power and increased the life time. Output voltage is adjustable by potentiometer. BCM/CCM control optional by selecting different daughter board. Optional switching frequency limitation on BCM allowing IGBT as the switching device. 206 Fairchild Semiconductor Corporation RD-549 Rev..0

2 . BCM PFC Control Daughter Board This daughter board contains an Interleaved Dual CrCM (BCM) PFC Controller FAN96MX and the peripheral components. Please refer to the FAN96 Product Folder for more information about the device. Key Features of FAN96MX Sync-Lock Interleaving Technology for 80 Out-of-Phase Synchronization Under All Conditions Automatic Phase Disable at Light-Load Dead-Phase Detect Protection 2.0 A Sink,.0 A Source, High-Current Gate Drivers High Power Factor, Low Total Harmonic Distortion Voltage-Mode Control with (V IN ) 2 Feed-forward Closed-Loop Soft-Start with User-Programmable Soft-Start Time for Reduced Overshoot Minimum Restart Frequency to Avoid Audible Noise Maximum Switching Frequency Clamp Brownout Protection with Soft Recovery Non-Latching OVP on FB Pin and Latching Second-Level Protection on OVP Pin Open-Feedback Protection Power-Limit and Current Protection for Each Phase Low Startup Current of 80 µa Typical Works with DC and 50 Hz to 400 Hz AC Inputs Additional Frequency Limitation The switching frequency of the FAN96 is limited between 6.5 khz and 525 khz. Since it s too high for the high power switching device especially for the IGBT, we setup an additional frequency limitation circuit for the option to decrease the switching loss when needed. This circuit is composed by a Dual Re-triggerable Monostable Multivibrator using the 74VHC23AM and peripheral components, shown in Figure. The output of the monostable multivibrator inhibited the falling edge of ZCD signal during the high level period which is triggered by the gate drive signal. The frequency of limitation is determined by the period of high level. It can be adjusted by C3, R25 and C4, R29. The frequency limiter can be disabled by removing the D, D2 or R22, R26. More information about the monostable multivibrator, please refer to the 74VHC23A Product Folder. 206 Fairchild Semiconductor Corporation 2 RD-549 Rev..0

3 PCB Layout Tips for FAN96 The PCB layout is critical for the interleave BCM PFC especially in the high power solutions because the sensitivity of the Zero-Current Detection (ZCD) signal is very easy influenced by the switching noise of the alternating channel. The OCP level of the FAN96 is 0.2 V. The low trigger voltage is helpful to decrease the power loss on the current sense resistors, it also makes the OCP miss-trigger easily. If the sensitive input signal is not carefully considered, the PFC may be unstable. Below are recommendations to avoid this issue: () Use differential path on the ZCD winding. An often mistake of layout on ZCD winding is connecting the GND pin to nearby GND copper directly. The correct way is connect the GND pin of winding to pin 5 of the FAN96. Please refer Figure 4. (2) The path of CS signals should be close to the GND path which connects pin of the FAN96 and the switching devices. (3) Drive switching devices by Totem poles instead of driving directly. The Totem poles need to be close to the switching devices. The drive ability of the FAN96 is big enough, but if we drive the switching device by the FAN96 directly, the charge/discharge current of the input capacitance of the switching device will add noise on the GND path between IC and switching devices. This noise will insert to the CS pins further more... Photographs Figure. BCM PFC Control Daughter Board 206 Fairchild Semiconductor Corporation 3 RD-549 Rev..0
