Now, take the excited and self-motivated fishermen as an example. Both of them convert low-voltage direct current into high-voltage alternating current, and then convert it into direct current in the form of voltage doubling rectification or bridge rectification.

The output modes are monocrystalline silicon, dual silicon, tetrasilicon, triode, IGBT and so on. Each has its advantages and disadvantages. Monocrystalline silicon has great lethality, bisilicon is good for floating fish, tetrasilicon has high voltage, large area and small triode area, but it has good fish control ability.
