What is the meaning of 230V ac and 50Hz ac supply?
It is an AC supply with an rms voltage of 230 v and a frequency of 50 Hz, as used throughout Europe.
What is the Difference between frequency converter and frequency inverter?
frequency is genrally cycle per second, and frequencies may be of a dc nature or ac , devices which convert dc frequency in to an ac frequency are frequency converters and devieces which convert ac frequency in to dc frequency are frequency inverters. because in terms of power electronics, devices which convert ac to dc are called converters, and devices which convert dc in to ac are called "inverters" 'mehboob hunzai" I'm a engineers in this devices, the frequency inverter is convert AC to AC but with variable frequency output, means the frequency & voltage are adjustable; The frequency converter can convert DC to AC, like 24VDC to 220VAC and also the frequency is adjustable. One most important thing is the out power of frequency inverter just can be used for controlling AC motor, while frequency converter can be treated as normal power supply as our daily using power grid.

Formula how to calculate voltage ripple peak to peak?
For Half wave rectification: Vr(HW) = I/(C*F) HW= Ripple Voltage I = Direct Current C= Capacitance F= Frequency of the ac line. For full wave rectification: Vr(HW) = I/(2*C*F)
What factors determine power?
Power = Current * Voltage * Power FactorAbove expression can further be explore as :1. For DC CircuitsPower = Current * Voltage2. For Single Phase AC CircuitPower = Current * Voltage * Power Factor3. For Three Phase AC CircuitPower = Line Current * Line Voltage * Power Factor
Speed control of three phase induction motor by supply voltage control using AC voltage regulators?
No. Use standard utility AC, 3 PH voltage to feed a Variable Frequency Drive (VFD). The VFD is then wired to the motor. The output of the VFD varies average voltage and frequency in a semi-constant proportion to keep Volts/Hertz ratio the same to the motor. The operator can then adjust or select the desired speed from the VFD and the VFD will run the motor continuosly at that desired speed. If you were to control only voltage to the motor without adjusting frequency in proportion, the motor would burn up.
What is frequency the current alternates in the US?
In the US AC current oscillates at 60 Hz.http://www.answers.com/alternating+current
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
Is voltage related to frequency?
Voltage and frequency are related in AC (alternating current) systems. In AC circuits, voltage is directly proportional to frequency according to the formula V = 2πfL where V is voltage, f is frequency, and L is inductance. This relationship is important in analyzing and designing electrical systems.
How do you step down frequency and voltage from an AC generator?
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
Why freqvency in AC and Why not in DC Voltage?
In AC voltage, frequency refers to the number of complete cycles per second that the voltage alternates direction. This is because in AC voltage, the direction of current flow continuously changes over time. In DC voltage, there is no alternation of direction, so frequency is not applicable.
How does the maximum value of the current depend on the frequency of the AC voltage source?
The maximum value of the current in an AC circuit depends on the frequency of the voltage source. As the frequency increases, the maximum current value also increases.
What is the voltage in phone line in Pakistan?
there is 100 ac Voltage in phone line in Pakistan
Rate in which ac voltage waveform periodically repeats itself?
Frequency.
How does a frequency inverter work?
A frequency converter converts alternating current of one frequency to alternating current of another frequency. Generally it's used for controlling the ac motor speed by changing the supply frequency.
Dc and ac analysis of Differential amplifier?
DC Analysis: For this analysis, frequency is made zero and the voltage of the source is increased in small steps from 0V.And the output voltage is plotted. So, finally we get a Vout vs Vin curve. AC Analysis: In this analysis, we choose an AC source. We keep the Offset voltage = 0V, AC voltage or small signal voltage = 2V (You can take any voltage you wish and it doesnt matter). So, to plot the ac response or frequency response of the circuit, increase the frequency in steps and note the output voltage. from this analysis , we can find the gain of the circuit over frequency.
What is the function of variable frequency drive?
The function of a frequency drive is to control the speed of an electric motor. In general, a frequency drive converts the ac supply voltage into a dc voltage and then converts this dc voltage into a ac voltage of which the amplitude (voltage) and the frequency can be varied. Giving you the possibility to fully control the speed of the motor. Applications: (big) ventilators, pumps, cranes, elevators and virtually all other applications where electric motors are used.
How does DC differs from AC?
The AC current oscillates with cycle time to time.
