1.1.2 Diode Rectifier & Filter

We use the Full-Bridge Rectifier to minimize the loss Base on the figure above, we have the formulation:

𝑣𝑆= 2 × 𝑉𝐷𝑖𝑜𝑑𝑒+ 𝑣𝑜𝑢𝑡−𝑟𝑒𝑐𝑡𝑖𝑓𝑖𝑒𝑟

⟹ 𝑣𝑜𝑢𝑡−𝑟𝑒𝑐𝑡𝑖𝑓𝑖𝑒𝑟= 𝑣𝑆− 2 × 𝑉𝐷𝑖𝑜𝑑𝑒= 22√2 − 2 × 0.7 = (𝑉) 29 71

Choose 𝐶 =100𝑚𝐹⟹ 𝑍𝐶=𝜔𝐶1= 2𝜋𝑓.𝐶1 = 2𝜋 .50 100 101 × −3= 0.03 Ω (𝑣𝑒𝑟𝑦 𝑠𝑚𝑎𝑙𝑙) So 𝑣𝑜𝑢𝑡−𝑓𝑖𝑙𝑡𝑒𝑟≈ 29 71 𝑉

Base on the figure above, we also have: 𝐼𝑙𝑖𝑚𝑖𝑡= 𝐼𝑧𝑚𝑎𝑥 + 𝐼𝑜

⟺𝑣𝑜𝑢𝑡−𝑓𝑖𝑙𝑡𝑒𝑟𝑅 − 𝑉𝑧

𝑙𝑖𝑚𝑖𝑡 = 𝐼𝑧𝑚𝑎𝑥 + 𝐼𝑜

⟺29.71 − 10𝑅

𝑙𝑖𝑚𝑖𝑡 = 40 10× −3+ 1.2 ⟹ 𝑅𝑙𝑖𝑚𝑖𝑡= 15 89 Ω
