Non-isolated high-power LED drivers have become increasingly popular in recent years and have begun to become the development direction of high-power power supplies because they have unique advantages over isolated drivers. Here are some advantages of non-isolated high-power LED drivers:
01 High cost performance
One of the main advantages of non-isolated high-power LED drivers is their cost performance. Non-isolated drivers do not require any isolation transformers or other peripheral components, making them a cheaper option for many LED lighting applications.
02 smaller size
Non-isolated high-power LED drivers are smaller and lighter than isolated drivers, and are easier to integrate into various LED lighting fixtures. This is particularly beneficial in space-constrained applications such as mobile lighting or portable lighting.
03 Higher efficiency
Non-isolated high-power LED drivers are more efficient than isolated drivers, with a difference of at least 2%. Non-isolated drivers will produce less energy loss or lower operating costs. This is due to the removal of the isolation transformer, which creates additional power losses and reduces efficiency. For high-power power supplies, a 2% efficiency difference translates into a 20% power savings.
04 Easy to integrate
Due to their faster response to dimming control signals, non-isolated high-power LED drivers are easy to integrate with a wider range of control and dimming systems, making them a versatile choice for many LED lighting applications.
05 Lower EMI
Non-isolated high-power LED drivers are generally less sensitive to electromagnetic interference (EMI) than isolated drivers because the isolation transformer in the isolated driver can generate more EMI, which can interfere with external electronic equipment or systems. Non-isolated drivers do not have this problem, making them a better choice when solving EMI problems.
06 Better thermal management
Non-isolated high-power LED drivers generally have better thermal management than isolated drivers because they do not require the additional space required for an isolation transformer, allowing for better heat dissipation and longer life.
Generally speaking, non-isolated high-power LED drivers have a series of advantages over isolated drivers, including cost-effectiveness, smaller size, higher efficiency, ease of integration, lower EMI, and better thermal management. While high-power isolated drivers are still widely used in many LED lighting applications, the advantages of non-isolated drivers make them a more competitive choice for lighting designers optimizing LED lighting system performance and cost.
