In today's electronics industry, switch mode power supplies (SMPS) have become a widely used power solution. They are favored due to their high efficiency, small size, and wide application. However, some key challenges faced during the design process often affect their performance and stability. Among them, transistor timing issues and the selection of bootstrap capacitors are critical.

Low leakage current is a critical requirement in the design of medical power supplies, particularly because of the potential risks associated with electrical shocks to patients and operators. Leakage current refers to the unintended flow of electrical current from a device's conductive parts to the ground or to other conductive parts, which can occur even when the device is operating normally.

SiC (Silicon Carbide) and GaN (Gallium Nitride) devices are widely used in high-efficiency power systems, including power adapters, but their aging mechanisms differ due to their unique material properties. In this article, we'll compare the aging behaviors of SiC and GaN devices, focusing on the implications for power adapters, and how device aging impacts performance, reliability, and lifetime in applications requiring high efficiency and compact form factors.

Medical power supplies are subject to rigorous requirements to ensure safety, reliability, and compatibility with medical devices. These requirements cover a wide range of factors, including regulatory compliance, electrical performance, environmental considerations, and mechanical design. Here’s an overview of the key requirements for medical power supplies

Medical-grade power adapters, also known as medical power Supplies adapters, are specifically designed to meet the rigorous safety and performance standards required by the medical industry. These adapters are subject to stricter regulations than standard power supplies, ensuring they can withstand harsh environments and minimize the risk of electrical hazards.

Power supplies are essential components in various electronic devices, transforming the alternating current (AC) from the power grid into the direct current (DC) required by the equipment. To ensure safety and reliability, different standards have been established by organizations such as the National Electric Code (NEC) and the International Electrotechnical Commission (IEC). So what are the main differences between NEC Class 2 and IEC Class II power supplies?
