    Three elements of low ripple power supply
    The following are the three elements of a low ripple power supply:1. Energy storage inductance. The larger the Q value of the energy storage inductance at the working frequency, the better. Many people only pay attention to the inductance. In fact, the influence of Q value is much larger. As long as
Precautions for module power application
1. Extremely light loadGenerally, the module power supply has a minimum load limit, which varies from manufacturer to manufacturer, and is generally about 10%. When the load is too light, the energy storage element will have difficulty in freewheeling and current discontinuity will occur, resulting
