  1. Rectifier Concepts Basic Concepts Pure resistive load Inductive load Load with an internal DC voltage TexPoint fonts used in EMF. Read the TexPoint manual before you delete this box.: AAAAAAA

  2. Single-phase bridge rectifiers Idealised circuit with

  3. When the source voltage is zero and increasing, we call it t = 0. Just prior to that instant, diode D3 is conducting and the voltage at the top of the diode is approximately zero volts. Let i(t) be the inductor current; load current Id. When D3 is conducting. Note that i(0) is zero and when D2 turns off the inductor current is Id.

  4. Single-phase bridge rectifiers Idealised circuit with Effect of on current commutation

  5. Single-phase bridge rectifiers This equation gives the final time.

  6. Three-phase, full-bridge rectifiers Idealised circuit with

  7. Three-phase, full-bridge rectifiers Effect of on current commutation Tutorial problems – 5-1, 5-3, 5-4, 5-11, 5-23, 5-25.

  8. Maple Script is: restart; currentdir("C:\\wattle\\courses\\PowerElectronics\\maple\\"); read "scrPracticalPage133.ma"; scrfw1phase-2.cir has the pSpice script to simulate it.

  9. Tutorial Problems • 6-1 • 6-3 • 6-5 (b) DPF = 0.707, PF = 0.636, THD = 48.55%. (c) DPF = 0.5, PF = 0.45, THD = 48.43%. • 6-9 • 6-12 • 6-18
