Virtual Laboratory for Power Electronic Based Reactive Power Compensators
Tehnicki vjesnik - Technical Gazette, 2018 The practical application is important in engineering education. However, in some cases, such as fund deficiency, practical applications may not be possible. In addition, this case restricts closely to pursue the novel technologies. Depending on developments in power electronics and microprocessor fields, use of Flexible Alternating Current ...
