Abstract: A power supply system with dynamic current sharing includes a current-sharing bus and a plurality of power supply units connected to each other through the current-sharing bus. The current-sharing bus provides a first current signal. Each power supply unit includes a local current bus for providing a second current signal. The active current-sharing unit compares the first current signal with the second current signal to generate a compensation voltage. The current-averaging unit compares a difference value between an average value of the first current signal and an average value of the second current signal to generate an average voltage. The droop current unit receives the second current signal to generate a droop compensation voltage. The integration calculation unit makes output currents of the power supply units be approximately equal according to the compensation voltage, the average voltage, and the droop compensation voltage.

The system board includes a first upper surface and a first lower surface opposite to each other. The electronic module spatially corresponds to the first upper surface and includes plurality leading pins and a carrier. Each leading pin has a soldering surface and is connected to the first upper surface through a first reflow soldering process. When the plurality leading pins are connected to the first upper surface, a height difference is formed between the carrying surface of the carrier and the soldering surfaces. The adhesive material is disposed on the carrying surface or the first upper surface. The carrier is connected with the first upper surface through the adhesive material, so that the electronic module is fixed to the first upper surface through the adhesive material.

Abstract: The present disclosure a program burning device configured to read or write to a program burning interface. The program burning device includes a microprocessor, a programming drive circuit and an overcurrent protection circuit. The microprocessor outputs a first test signal or a second test signal. The programming drive circuit outputs a high driving voltage or a low driving voltage to the program burning interface. After the programming drive circuit outputs the low driving voltage for a preset time, the programming drive circuit outputs the high driving voltage to make the program burning interface form a high impedance. Afterwards, the overcurrent protection circuit receives the first test signal to trigger the overcurrent protection, and then receives the second test signal to trigger the undercurrent protection. If triggering the overcurrent protection and the undercurrent protection are continuously failed over a preset number of times, the microprocessor determines that current protection is failed.
