AC DC Power Module Filling Requirements Potting and sealing of AC DC power modules is very important. This process involves not only the protection of AC and DC power modules (waterproof, moisture-proof, dust-proof, anti-corrosion, etc.), but also the thermal design of AC and DC power modules. Power module potting materials are generally divided into three categories: epoxy resin, polyurethane, and silicone rubber Due to the hardness of epoxy resin, it cannot be used for stress-sensitive and module packaging and SMT components, so it is basically eliminated in module power supplies. But epoxy resins are also used in cost-critical micropower power supplies due to their low cost. Some domestic bad power supply manufacturers also use this epoxy resin for AC and DC power supply modules, but due to stress problems, the failure rate of this power supply is very high, and buyers are very distressed. At present, most of the power modules are sealed with molded silicone. For the convenience of operation, the ratio of 1:1 is usually adopted. When designing for AC and DC power modules, attention should be paid to their thermal conductivity. However, the adhesion is not very strong, so a substrate coating can be used to improve...

DC means direct current. DC current is defined as unidirectional current. In a DC current, electrons move from a region of negative charge to a region of positive charge without any change in direction. This state persists despite alternating current, in which current can move in both directions. DC can pass through conductive and semiconducting materials. Electricity is defined as the flow of electrons through a conductor such as a wire. Current builds up in two ways, alternating and direct. The main difference between AC and DC current is the direction of electron movement. DC-DC is realized with the idea of ​​switching power supply. There are two types of DC-DC, buck and boost, which are called buck here. For example, input 10V in DC-DC. There are oscillator and chopper modules inside the DC-DC.     Advantages of using power modules There are now many different power modules in the market from different suppliers, but depending on the product, a power module is better than an integrated solution because using a power module saves development time and brings products to market faster. Power modules also offer the following advantages: 1. Each unit can be strictly tested individually to ensure products with...
