The PMP23461 reference design is a 4kW, bidirectional, CLLLC converter. The design employs a full-bridge CLLLC converter with synchronous rectification. The CLLLC utilizes both frequency and phase modulation to regulate the output across the required regulation range. The design uses a single processing core inside a TMS320F28388D microcontroller to control CLLLC. Synchronous rectification is implemented by the same microcontroller with Rogowski coil current sensors. High density is achieved through the use of highspeed GaN switches (LMG3522). The CLLLC runs with a variable frequency from 250kHz to 800kHz.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
