Six-phase converters

High-power converters don't use single-phase supplies. Three-phase rectifiers with a balanced load on each phase do not generate triplen harmonics (3rd, 9th, 15th, etc) at their power inputs.

  • True and False Questions about Transformers

    As mentioned above, in an ideal transformer, average power input = average power output. In a practical transformer, on account of losses, power output < power input.

  • Calculate the delay angle (alpha)

    If the average output voltage is 25% of the maximum possible average output voltage, calculate the delay angle (alpha). See Attached File. The average output voltage is proportional to the Cosine of the delay angle.

  • Looking at feedback and some Opamp problems

    * The common mode voltage should be within +/-12V for +/-15V supply. * The output impedance is about 75 Ohms. * The voltage gain rolls off 6dB per octave starting at 100kHz.

  • Average current and average voltage

    What is the average voltage across the load? What is the average current through the load? Since the 10-to-1 step down transformer is used, the output of the transformer will be: 120/10 = 12 V (rms) at 60 Hz.
