In the process of designing series resonance, the principle of multiple fHVHIPOT separation is mainly adopted, which can effectively meet the requirements of equipment for high voltage and low current during use, and this design will also be more convenient during use.
Series resonant devices are generally designed with high voltage and high current during testing, so their power supply capacity is relatively small in the design process. This can effectively minimize the losses in the entire power supply during use, so the energy consumption of this equipment is generally relatively low during use. Secondly, for the convenience of use, the volume and weight of this device are relatively small in the design process. This not only saves the cumbersome high-power modulation time, but also effectively reduces the footprint during use, making it more convenient to use.
Secondly, in the process of designing equipment, some output voltage forms are generally used to effectively prevent various radio waves from damaging the product. Secondly, in order to prevent short current from causing burns to the equipment during use, there are generally some safety protection designs in the design of series resonance. After a fault occurs, the circuit will quickly detach for a period of time, which will not damage the equipment or affect the normal use of the product. Therefore, in the process of use, the security of this device will also be safer than some other devices. This is also one of the many characteristics of series resonance.
