How to Solve the Problem in Power Supply Design

No matter the LED panel light or LED light tube, there should be the power supply in the light. In the design of the power supply of the LED panel light and wholesale LED panel light, we have a lot of challenges to overcome. Electromagnetic interference (EMI) is any conduction or electromagnetic effects associated with voltage and current generated. It will reduce the performance of a device, equipment or system. To solve the problem of LED power supply EMI, engineers have to consider the main aspects: circuit measures, choice of EMI filter, components, blocking and anti-interference when designing printed circuit boards, etc. For design engineer of LED panel light or LED tube light power supply, the electromagnetic interference problem always exists in the design process. How to solve the problem has been a hot issue.

To solve the problem of electromagnetic interference in gu10 LED bulbs china drive power supply, we can solve from the following several aspects:
1. Reduce the interference of switch power supply itself. First to be introduced is soft-switching technology. Add the inductance and capacitance element into the original hard switching circuit. Use the resonant inductance and capacitance to reduce switch du/dt and di/dt. When the switch device is turned on, the voltage drops before current rises. Then the overlap of voltage and current can be eliminated.

2. The choice of components matters a lot. Choose components which are difficult to produce noise, conduction and radiation noise. In particular, usually pay attention to choosing diode and the selection of transformer winding components. The ideal components are diode of fast recovery.

3. Improve the electromagnetic compatibility design of PCB. PCB is LED support for circuit components and devices in power system. It provides the electrical connection between the circuit components and devices. With the rapid development of electronic technology, the density of PCB is becoming higher and higher. The quality of PCB design for LED power supply system has great influence on electromagnetic compatibility.

By solving the problem of electromagnetic interference in LED panel light and LED light tube drive power supply, we can improve the quality of the whole LED lighting design. We have seized the technology to solve the problem of electromagnetic interference in power supply. You can trust us and we are sure to provide the best LED panel lights and LED light tubes for you.
