Miniaturization of High Voltage Power Supply for Portable Electrostatic Filtration

Electrostatic Precipitation (ESP) is an effective method of removing particulates from the air. It is currently used in many large-scale industrial applications but sees limited use in smaller-scale cases due to the difficulty of generating high voltage in small packages. Additionally, safety concerns prevent the widespread use of this effective technique. This paper presents the motivation, design, and evaluation of a miniature high-voltage DC (HVDC) power supply for applications in small-scale ESP systems. The power supply’s potential for portable ESP application is tested on a personal protective device, the so-called Smart, Individualized, Noncontact, Extended-Wear (SINEW) mask. The results show that the power supply operates with acceptable efficiency and generates high voltages and power necessary to drive ESP setups in practical applications.
