AC Input Adaptation: Receives a wide range of 90-264VAC alternating current, and suppresses high-frequency interference in the power grid through a filter circuit (such as an EMI filter) to ensure pure input power.

Rectification and Preliminary Filtering: Converts alternating current into pulsating direct current using a bridge rectifier, and then performs preliminary filtering through electrolytic capacitors to smooth the voltage waveform.

High-Frequency Switching Conversion: Drives power switching tubes (such as MOSFET or IGBT) through a PWM (Pulse Width Modulation) controller to convert direct current into high-frequency pulse signals (usually with a frequency of tens to hundreds of kHz).

Energy Transfer of Magnetic Components: High-frequency pulse signals undergo energy transfer and voltage transformation through transformers or inductor components (core magnetic components) inside the module. Take the transformer as an example:

Magnetic Flux Stability Control: Real-time monitoring of output voltage/current through a feedback circuit, adjusting the duty cycle of the PWM signal to control the magnetic flux change of the magnetic components, ensuring stable output voltage (such as ripple and noise <50mVp-p).

Secondary Filtering and Voltage Stabilization: The pulse direct current output from the secondary side is further smoothed by a Schottky diode rectification and an LC filter circuit (inductor + capacitor) to form a stable DC voltage (such as 56VDC).

Closed-Loop Feedback Control: The sampling resistor at the output end feeds back the voltage/current signal to the control chip, which adjusts the PWM signal after comparing it with the reference voltage to achieve dynamic voltage stabilization (efficiency can reach 90%).

Implementation of Protection Functions:

Thermal Management Logic: The module adopts a natural convection cooling method, derives the heat of internal components (such as power tubes and transformers) through a metal shell and heat sink. When the temperature exceeds the set threshold (such as the 70°C operating upper limit), if heat dissipation is not timely, over-temperature protection (OTP) may be triggered.

Environmental Compatibility Design: Through moisture-proof and seismic materials (such as potting adhesive for fixing components) and wide-temperature design (-20~70°C operating temperature), it ensures the stability of magnetic components and circuits in harsh environments.
