Features• Power ratings:

– input DC voltage: 375 V to 425 V– output voltage: 48 V– maximum output current: 62.5 A– output power: 3 kW– peak efficiency: 95.3%– HF transformer isolation voltage: 4 kV

• Resonant and switching frequencies:– max DC-DC switching frequency: 380 kHz (at startup)– closed loop switching frequency: 120 kHz to 250 kHz– resonant frequency: 175 kHz

• Protection mechanisms:– undervoltage and overvoltage protection on input and output– overtemperature protection– short-circuit protection– forced cooling with air flow speed modulation according to the output power

and temperature• Efficiency:

– adaptive synchronous rectification– light load burst mode

• Digital control with STM32F334 microcontroller

DescriptionThe STEVAL-DPSLLCK1 is a digitally controlled 3 kW full bridge LLC resonant DC-DC converter with output synchronous rectification. The kit consists of a power board,digital control board, adapter board, and firmware modules.

The full bridge primary section of the LLC converter is based on MDmesh™ DM2Power MOSFETs for high efficiency performance. The PWM switching frequency isdigitally controlled to regulate the output voltage. The converter operates at nearresonant frequencies to maximize efficiency and achieve Zero Voltage Switching(ZVS) over the entire operating range.

The HF transformer provides galvanic isolation and magnetic integration of theinductive elements for a compact design.

Synchronous rectification (SR) with STripFET™ F7 Power MOSFETs is employed onthe secondary side to reduce conduction losses.

The STM32F334 microcontroller on the digital control board embeds a highresolution timer for finer regulation and can communicate status information viaUSART, CAN, SMBus, and opto-coupled serial communication.

Both the primary and secondary sections are supplied by an off-line flyback circuitbased on VIPer27HD which provides regulated voltages to the control board, thegate driver ICs and the signal conditioning circuits.

You can connect a PFC to the power board and extend communication andinterfacing with the supplied adapter board.
