README
README.mdSpotcar Inversora
Projeto TCC, constituindo uma repuxadeira elétrica. Planilha de cálculo no arquivo Planilha_de_Cálculo.pynb; separado nas seguintes partes:
- "Kicad - Projects" - placas que serão construídas, inclui versões alternativas que não serão utilizadas
- "Spotcar Codebase" - código do microcontrolador escolhido
Visão Geral
- Visa principalmente reduzir volume, peso e custo do produto atualmente no mercado (50x40x40cm e 19,5 kg)
- Deve ser capaz de realizar solda por resistência através da ponteira de solda (mínimo 10A, máximo ~200A)
- Utilizada para desamassar peças metálicas de carros - não recomendada para lataria de alumínio
Especificações Técnicas do Sistema
- Tensão de entrada 220 V @ 60 Hz
- Potência nominal de saída 2 kVA
- Corrente máxima de saída 200 A
- Frequência da corrente de saída 40 kHz
- Tensão RMS de saída em vazio 10 V (onda quadrada)
- Tecnologia inversora (Dada a potência, provável o uso de IGBTs)
- Proteção de sobrecorrente, sobretemperatura e possívelmente subtensão na entrada
Topologia
Devido à potência relativamente baixa e para reduzir a complexidade do comando - foi escolhida a topologia meia ponte.

Questions
How big is the Panelized Inv Spot Disp PCB?
It measures 258.6 × 152.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Panelized Inv Spot Disp use?
156 parts, built around the LKS561, AMS1117-3.3, L7805 and LTV-817S. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Panelized Inv Spot Disp KiCad files?
From the Emanuel600/Spotcar-Inversora repository on GitHub, at the commit this page was made from: the board is Kicad - Projects/Inv_Spot_Disp/Panelized-Inv_Spot_Disp.kicad_pcb and its schematic Kicad - Projects/Inv_Spot_Disp/Inv_Spot_Disp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panelized Inv Spot Disp design in my own project?
Its repository states no licence, so its author keeps all rights: ask Emanuel600 before reusing the design.
