Development

This part containts developement milestones with accompaning documents.

1. Technical requirements

The technical requirements for O-ESD hardware are summarized along with review of multiple ESD guns available on the market. Technical specifications of hardware on the market are compared to the specification from IEC61000-4-2 standard.
Technical requirements

2. Schematics and considered realizations of high-voltage generator for O-ESD

Various approaches considered as possible solutions for O-ESD are given along with the schematics in LTspice program.

3. Trade-offs and cost-benefit analysis of considered solutions

The cost-benefit analysis of considered solutions is done by taking into the account the availability of electronic components on website of online distributors of electronic components. The understood trade-offs for considered solutions are given.

4. Design and prototype printed-circuit boards for all candidate solutions

All considered solutions are prototyped. Since some candidate solutions share some components or parts, PCBs/protypes are made for functional parts that can be mixed and matched between O-ESD solutions. For all considered parts that have PCB, gerber and drill files (needed for the production) are given. The photos of prototypes, functional parts and considered components are provided, too.

5. Prototype assembly (v0.1) and microcontroller software

Three prototypes are assembled (v0.1). Prototype photos.
Microcontrollers are tested on ESD. Report, photos and codes for ESD testing of microcontrollers.
Software for microcontrollers for user interface is written. Software for user-interface.
Based on testing results: new double cascade is designed in KiCAD, PCB for flyback and push-pull is designed in KiCAD, new trafos are designed and assembled and DC/DC converters and battery chargers in power supply are considered.
