Variable frequency electronic generation of sinusoids first requires the grid AC to be rectified into DC. Next the DC is converted to high f AC by an inverter circuit. The entire process is at 95% efficiency. Below you are required to refresh your understanding of AC to DC rectifiers. Diode rectifiers are non-linear loads so grid power factor and harmonic generation are again a consideration. The total power factor is composed of two parts: the distortion power factor due to...

1. Is the power supply for a transformer AC or DC? Explain in detail why only this type of power supply will work. 2. Some configurations with the iron core have low efficiency while others have high efficiency. What is the iron core doing to cause this? Be specific. (Hint: think about how a transformer works.) 3. For an ideal transformer the energy must be conserved, so the average power (P=IV) in the two circuits must be equal. Therefore, if...

The two-quadrant chopper is used to control the speed and regenerative braking mode of a DC motor with a motor constant of 0.1 V/rpm, and Ra = 0.2 ?. Consider a ripple free current. The chopping frequency is 250 Hz and the supply voltage is 120-V dc. S2 and D2 are operated for regenerative braking of the motor. At the speed of n = 350 rpm and an average output current of -100 A. (a) Determine tON. (b) Draw waveforms...

DC-AC inverters have many commercial and residential applications, including uninterruptible power supply (UPS) units, adjustable speed drives (ASD) for AC motors, and electronic frequency changer circuits. They are also used in solar electrical systems where batteries are charged from solar panels and used as the input DC voltage source. The inverter circuit converts the DC into AC voltage of desired frequency. Most of us are also familiar with HVDC transmission systems, where high voltages are first converted from AC to...
