Abstract

The invention discloses an integrated PCB-level melt-blown electret power supply topology, and the electret power supply does not need an additional high-voltage pack and directly realizes the function of the high-voltage pack on a PCB by using a boosting transformer and a high-voltage uncontrolled rectifier bridge. The melt-blown cloth electret power supply topology comprises the following components: an alternating current power supply Va, a first filter capacitor C1, a second filter capacitor C2, a first voltage-sharing resistor R1, a second voltage-sharing resistor R2, a resonant inductorLr, a resonant capacitor Cr, a board boost transformer T, a first switch tube MOSFET M1, a second switch tube MOSFET M2 and a plurality of diodes. Compared with the traditional melt-blown cloth electret power supply, the integrated PCB-level melt-blown electret power supply topology does not need the additional high- voltage pack, and all elements are integrated on the PCB, so that the productiondifficulty is simplified, the size of the power supply is reduced, and the integration level and the power density are improved.

Description

technical field [0001] The invention relates to the technical field of electret power supply for melt-blown cloth, in particular to an integrated PCB board-level melt-blown cloth electret power supply topology. Background technique [0002] High-pressure electret treatment technology is the core technology to improve the virus adsorption effect of melt-blown cloth and meet the N95 standard. The shortage of high-pressure equipment and the uneven performance are the key factors restricting the quality and output of masks. However, the discrete circuit combined with the inverter circuit and the high-voltage package used in the traditional melt-blown cloth electret power supply is not conducive to the overall design of the circuit, and it also makes it difficult to reduce the weight and volume of the electret power supply, and the power density is low. For this reason, the present invention proposes an integrated board-level melt-blown cloth electret power supply, which uses a ...
