5. Three aspects of electromagnetic pulse protection
5.1. Shielding: Shielding makes use of shielding body to block or reduce the transmission of electromagnetic energy to achieve electromagnetic protection, allowing no electromagnetic field to reach the protected devices.
5.2. Grounding: Grounding is the connection between the electronic devices and the earth through appropriate methods and approaches in order to improve the stability of electronic equipment and effectively restrain the influence of external electromagnetic field, avoiding the interference and damage caused by discharging, which is cause by charge accumulation.
5.3. Filter: A filter can be formed into selective network with resistance, inductance and capacitance to achieve the filtering effect. A filter can also be made of lossy material such ferrite to filter. (Reference: Sun yongjun, Principles and Protection of Electromagnetic Pulse [J], Space Electronic Technology, 2004 (3))
6.

- blocking all possible channels of surge include blocking the channel between the lines and the ground to create a perfect protection.
6.7. The capacitor design is hybrid multi-module with both thermal insurance and electric insurance.
6.8. The surge protection product is the only one that is earth-free, using patented sine wave tracking technology,
7. China Patent 201510334961.0 discloses an electromagnetic field shielding system for electric vehicle driving motor. This patent is a failure. The shell is not a closed coil, and the electromagnetic field can only generate voltage on the shell but can't induce current on it. So, the electromagnetic field will directly penetrate the shell.
Invention Content
The conditions for generating induced current are: a part of the conductor cuts the magnetic induction line in the magnetic field, which is that the moving direction of the conductor in the magnetic field is not parallel to the direction of the magnetic induction line; Second, the circuit is closed. The induced voltage is generated at both ends of the conductor that cuts the magnetic induction line in the magnetic field, which is a power supply. If the circuit is closed, the induced current will be generated in the circuit.
This application applies the above theorem to solve the problem that the existing motor shield can't shield electromagnetic field. The solution is making the motor controls the machine and the motor, and the magnetic field lines generated cut the coil, connecting the battery to form a closed circuit, so that the coil generates alternating induced current, which is rectified by a silicon rectifier to be DC and then stored in the capacitor and then stored in the battery. The system makes the electromagnetic field intensity of an electric vehicle less than 0.4 μt, thus achieving the purpose of eliminating the magnetic field in the shield.

And the first general shield or the second general shield of the power generation system consisting of coils, control circuits, capacitors and batteries is connected with the electronic control system. The electronic control system is connected with the super capacitor circuit. The super capacitor circuit is connected with the backup battery. and the backup battery is connected with the main battery.
The first total shield or the second total shield is connected with the electronic control system, and is used for generating the induced electromotive force through the movement of the motor controller and the motor inside the first total shield or the second total shield relative to the coil winding of the first total shield or the second total shield; The electronic control system filters, rectifies, multiplies and stabilizes the received induced electromotive force from the first general shield or the second general shield, and then obtains a suitable stable voltage, which is input into the super capacitor circuit, and the charge is stored in the super capacitor. The super capacitor circuit is connected with and charges the backup battery of the electric vehicle, and the backup battery charges the main battery of the electric vehicle. In the silicon rectifier circuit, the three-phase full-wave rectifier diodes are D1, D2, D3, D4, D5 and D6; the voltage stabilizing circuit includes the filter capacitor WD of C1 and the DC voltage conversion integrated circuit IC1; the super capacitor circuit includes two single capacitors C2 and C3 connected in series; the diode D7 prevents the current of the backup battery 6 from flowing back to the total shielded power generation system; and the IC1 is a wide input voltage DC-DC conversion integrated circuit.
Based on the fast-charging characteristics of supercapacitors C2 and C3, they are used as relay energy storage elements for charging Because the service life of supercapacitor is longer than that of battery, it will not pollute the environment after being scrapped, and it can directly replace battery as energy storage element. Combining the power characteristics of the capacitor with the high energy storage of the battery, the supercapacitor can be charged to any potential within its rated voltage range and completely discharged, while the battery is limited by its own chemical reaction to work in a narrow voltage range, and over-discharge may cause permanent damage.

Supercapacitors can store more energy than traditional capacitors with the same volume, and batteries can store more energy than supercapacitors with the same volume.
