BLK start threhold, controller enters into wakeup state. IPPC widens the control range of the LLC converter simplifies the design of wide input and output-voltage The Texas Instruments UCC25640x LLC resonant controllers include various features designed to control and protect the user's operation. DS00001477B-page 1 AN1477 ABSTRACT A half-bridge LLC resonant converter with Zero Voltage Switching (ZVS) and Pulse Frequency Modulation (PFM) is a widely used topology for DC/DC conversion. If digital power is on the table, the you can consider UCD3138 or C2000 for full bridge LLC. 5ms >200ms between Vin to PWM ( configurable) Vcc=4-15V TI’s UCC256402 is a LLC resonant controller with ultra-low standby power and high voltage startup. Crank up Your Power Supply with LLC Controllers. Refer to Figure 3 for placement of each macro block. The control effort is approximately linear high power factor. LLC structure’s main particularity relies on handling the power ow, by using fre-quency modulation instead of Pulse Width Modulation (PWM) like traditional converters. Home. TIDT253. The LLC topology utilizes the transformer leakage inductance as its resonant Charge−current control: Voltage−mode control, where the error−amplifier output voltage directly controls the switching frequency, has been typically used for LLC resonant converters. Any D, 1-D Application Specific PWM can be used from TI. 4 Implement Three-Phase Interleaved LLC on C2000 Type-4 PWM SPRAD15 – MARCH 2022 It integrates an LLC controller and PFC controllers operating in DCM and QR modes, enabling the construction of complete resonant power supplies. 00:33:57 | 11 APR TI LLC Controller (Image courtesy of Texas Instruments. com. However, the compensation network design of the LLC resonant converter is relatively challenging since the frequency response of the LLC resonant converter Watch this video to learn more about how the UCC25640x, new family of LLC resonant controllers, can impact the cumulative world power consumption. The EVM provides a platform to evaluate UCC25600 LLC resonant controller from a PFC input voltage and 12-V output rated at 300-W output power. Full microcontroller-based control of resonant LLC half-bridge DC/DC converter; 375-405V DC input, 12 DC output, 25A rated output (300W) SLS (SRC/LLC+SR) Controller with 1 FM+2 PWMs 2014/10/09 Rev2. TI’s UCC256303 is a LLC resonant controller enabling low standby power. TI’s products are provided subject to TI’s Terms of Sale or other applicable terms available either on ti. It achieves high PFC and minimum THD of AC input current. TI PROVIDES TECHNICAL AND RELIABILITY DATA As such, Infineon offers 2 types of resonant mode controller ICs, namely hybrid flyback (or commonly known as asymmetric half-bridge flyback topology) and LLC controllers. 3 Level T-type . 3 LLC Control Method A second approach is to mitigate the AC ripple in the LLC converter. View the TI PMP40586 reference design block diagram, schematic, bill of materials (BOM), description, features and design files and start designing. The PMP20795 reference design uses UCC256301 enhanced LLC controller with integrated driver to provide 24V/12A output from a nominal 380VDC input. I am using TMS320F280049C and planning to write code to control an LLC converter. The first one is full bridge at a power of 2kW and which looks like its design is conventional, the second one is the rogue one its push pull with 500W of power which increases the frequency as power need TI has developed the new UCC25710 LLC Resonant Half Bridge Controller, for Multi-String LED driver applications, with PWM dimming. 00:18:57 | 28 SEP 2018. • 400V-to-15V DC/DC macro – [M2] – Generates an isolated 15V from the 400V input voltage. ZCS avoidance feature and OVP sensing feature in LLC controller improves robustness and protects systems from overcurrent, short circuit, TI’s Control Law Accelerator (CLA) is designed to execute real-time control algorithms in parallel with the C28x CPU, effectively doubling the computational performance of C2000 devices. This C2000 real-time MCU based digital hybrid hysteretic controlled (HHC) LLC converter design demonstrates how current mode control achieves better transient response compared to a traditional voltage mode control with least CPU resources yet achieving the needed performance. This converter operates by creating a AHB requires a controller capable of producing D and 1-D outputs and TI has many controllers of this type. Evaluation board The MP6923 is a dual, fast turn-off, intelligent rectifier for synchronous rectification in LLC resonant converters. Boot capacitor is charged just before the softstart by applying a long LO pulse 6. In this video, we will explain the basics of resonant converter topologies and briefly introduce the popular LLC series resonant converter along with a design View the TI TIDA-00381 reference design block diagram, schematic, bill of materials (BOM), description, features and design files and start designing. 5% www.
