Problems solved by technology

[0004] In view of the ultra-low resistance of the farad capacitor, if the traditional wired charging method is used to charge the farad capacitor, the farad capacitor will be short-circuited at the moment when the power is turned on, which will easily lead to damage to the charger.

[0029] Example 2. Another principle of Farad capacitor charger

[0030] There are other options for implementing the Farad capacitor charger of Example 1:

[0031] Solution 1: Use a single-chip MCU to write the timing program and the oscillation and driver required for the launch, and add a power output tube outside the MCU to replace the timer T and launch driver IC1 in Example 1.

[0032] Solution 2: Use Hall (Hall) sensor instead of reed switch RD to realize the magnetic control function.

[0033] Example 3. Structural layout of Farad capacitor charger

[0034] like image 3 , the plastic shell P is divided into upper and lower shells, and the cavity H is used to place a PCB. The components on the PCB include: electronic switch K, timer T, resonant capacitor C1 and transmitting driver IC1, etc., transmitting coil L1 and dry reed Tube RD is placed on the other side of the cavity;

[0035] The position requirements of the transmitting coil L1 and the reed switch RD: the position of the transmitting coil L1 is aligned with the receiving coil L2 up and down, and the position of the reed switch RD is aligned with the magnet SN up and down, so as to ensure that the reed switch RD is connected when the magnet SN is close. At the same time, when the transmitting circuit is working, the receiving coil L2 can well receive the energy from the transmitting coil L1.
