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.

Is DC signal is periodic?
Yes DC is periodic with zero frequency........and undefined fundamental time period To........
What is the pulsating DC frequency?
When AC full wave is rectified into DC by using bridge rectifier .The DC do not actually behave like an ordinary DC and the DC has a constant value .In fact, it is in pulsating form.This is known as Pulsating DC.
Why frequency of DC current is zero?
frequency if it will not zero then we cant tell its dc ...AnswerFrequency is the number of alternations per unit time. As d.c. doesn't alternate, then zero divided by any quantity of time is zero!
How does A Frequency Converter circuit diagram look like?
Depends if you want to convert an RF signal to a different frequency, as all superheterodyne circuits do (most TVs and radios). That's called a frequency mixer. If you want to change a power line frequency to another, rectify it to DC, then chop with an inverter.
What is the frequency of 27 DC volts?
Basically, "frequency" applies to AC, not to DC. If you want to assign it a frequency, the frequency is zero. The amount of volts is not relevant.
What is frequency in relation to a battery?
dc does not have frequency only ac
Why use DC circuit when frequecy is zero?
DC has no frequency.

Is lighting AC or DC?
Mostly DC, but there is high frequency AC too.
Skin effect related to ac and DC?
IT IS RELATED TO AC ONLY BKZ SKIN EFFECT DEPENDS FREQUENCY ONLY WHERE IS IN DC NO FREQUENCY
Speed of DC Motor can be controlled by a frequency variable?
by using a frequency tuner in input we can change input frequency and in this way speed of dc motor will also vary. <<>> Varying the frequency (VFD) only works on AC motors.
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
Why frequency exist in ac but not DC?
the frequency of DC is 0 HzAnother AnswerThe term, 'frequency', describes one complete alternation in both magnitude and direction of an a.c. current. As d.c. changes neither in magnitude or direction, then the term frequency cannot be applied to d.c.
What instrument measures direct current?
Voltage . . . DC voltmeterCurrent . . . DC ammeterThe "ohmmeter" is also fundamentally a DC ammeter at heart.Frequency . . . DC doesn't have frequency.
What is use of RFC in Hartley oscillator?
it is a radio frequency choke which connects the dc supply to the circuit but isolate the dc supply from the high frequency oscillations generated in the feedback circuit
