Problems solved by technology

However, these types of charge pumps are all contact-separated charge pumps. Although the charge density has been gradually increased, they all have inherent shortcomings and deficiencies: First, the voltage and current generated by the contact-separated charge pump are based on There are sharp peaks in the form of pulse waves, which bring great difficulties to the smooth processing of voltage and current that subsequently power electronic components; second, the contact-separated charge pump needs a higher power to generate effective and large enough electric power driving frequency, which limits its range of application in low-frequency environments; third, the contact-separation charge pump requires a large installation space due to the necessary travel distance for ensuring material contact and separation, which also limits its scope of use
