Hello everyone, LCSC Electronic supplier MDD shared the MOS tube application solution for hair dryers. In the article, MDD analyzed the requirements for the circuit design of high-speed hair dryers and recommended MOS tubes that suit this solution.
High-speed Hair Dryers Circuit Design Requirements
The high rotational speed of the high-speed hair dryer is mainly from the DC three-phase brushless motor, which has the advantages of simple structure, high reliability, good speed regulation performance, long life, no reversing spark, high output torque, small size, and lightweight to combine with the hair dryer.
The traditional hair dryer serves to dry the hair at high temperatures. Excessive temperature will damage the hair quality. However, the high-speed hair dryer has temperature control chips. So the maximum temperature will not exceed 57 degrees. In addition, some high-speed hair dryers also offer hair care functions, such as essential oils and negative ions, to provide better hair protection.
Secondly, the weight of the high-speed hair dryer is light. Compared with the traditional hair dryer, the structure of the high-speed hair dryer is streamlined. Therefore, the size of the whole machine is smaller, and the weight is lighter, which is easier to carry.
Typical Application Topology and Application Cases
The full-bridge DC motor drive circuit is to accurately control the three sets of MOS through the program setting of the control center. To make the three-phase brushless motor work properly, we control the motor conduction of different phases with a specific turnover sequence. At the same time, through high-frequency switches, it increases speed and meets the air volume requirements of high-speed hair dryers.
The application of high-voltage MOS tubes in high-speed hair dryers is mainly to control the speed of the motor. MOSFET (Metal Oxide Semiconductor Field Effect Transistor) has a high switching frequency, a simple control method, a response speed, small incentive resistance, high reliability, etc. It is ideal for application in high-speed hair dryers.
