what is the difference between duty cycle and pulse width?
608051
Electrical and electronics In electronics, duty cycle is the percentage of the ratio of pulse duration, or pulse width (PW) to the total period (T) of the waveform. ... Similarly, for pulse (10001000) the duty cycle will be 25% because the pulse remains high only for 1/4 of the period and remains low for 3/4 of the period.

Both current and voltage waveforms are in-phase in going from primary to secondary. Primary and secondary currents are in-phase. Secondary current is stepped up by a factor of ten.

The on and off of the switch is controlled by PWM that generated by PIC microcontroller 16F877A. The on and off of the switch is important because the duty cycles of the PWM is used to regulate the DC output voltage. So the desire output voltage can be produced by generate various duty cycle.

PWM stands for Pulse Width Modulation technique , It is used to convert the digital signal into an analog by varying the width of the Pulse . The PWM pins are used for giving the desired analog output . They are used to set the LED brightness or to run Stepper or Servo Motor or anything which require analog inputs .

Frequency is how often a signal switch between low voltage and high voltage. Frequency is expressed in cycles per second, or Hz. Duty cycle is percent of time that the signal stays at high level. ... As an example, a 100MHz signal (100 million cycles per second) has a period of 10ns.

Hertz (Hz) = One hertz is equal to one cycle per second. Cycle = One complete wave of alternating current or voltage.

The VFD's Carrier (Switching) frequency is the frequency of the PWM (Pulse Width Modulation) pulses, i.e. the frequency at which the VFD's output transistors; usually IGBTs (Insulated Gate Bipolar Transistors), are switching. This typically ranges from 2 to 20 kHz.

The only difference here is the rated boost clock – the Pulse card runs up to 1366MHz, whereas the Nitro+ is slightly faster at up to 1411MHz. There are more differences when we compare the cards' features, however. The Pulse card is the cheaper unit, so it lacks a few features included with the Nitro+.

While period is measured in seconds per cycle, frequency is measured in cycles per second. Consider our wave with a period of 2 seconds. Since the wave completes one cycle every two seconds, then its frequency is one half or 0.5 Hz. So, you see - period and frequency are reciprocals of each other.

PWM can also effect the sound of your motors. -> It's more efficient to use PWM compared to, say, a resistor in series, as a lot power is dissipated through the resistor. It's also much easier to output a PWM pulse and is typically built into microcontroller's hardware nowadays.

A deep cycle battery is constructed differently than a cranking battery, with thicker, heavier plates. ... The cranking battery has more yet thinner plates to give a fast voltage spike to crank an engine, but is not intended to maintain high power output for long periods.

The Synchronous load is synchronous and this means that the count from the Q outputs will stay the same when it goes through the load input. ... The Asynchronous load input is different. Since it is asynchronous it delays the counters pulse by one when it counts up, it adds 1 to the pulse when it counts down.

Runtime is the time duration you want your batteries to backup for. Input is the UPS's battery input voltage. UPS with smaller power ratings require a single 12V battery while larger ones need 24V (2 batteries) or 36V (3 batteries).

Pulse Dose vs. Continuous Flow: The Difference. Pulse dose (PD) oxygen delivery is based on breathing and inhaling, which customizes your oxygen delivery to your breath rate. Continuous flow (CF), on the other hand, delivers oxygen at a constant rate, indiscriminate of the user's breathing.

A period of 1 second is equal to 1 Hertz frequency. Period is the inverse of frequency: 1 Hz = 1 cps. 1 Hertz: Hertz is the SI base unit of frequency defined as one cycle per second.

The difference is that Cranking Amps measures how much power is required to start a battery during normal climate (32 degrees Fahrenheit or 0 degrees Celcius) while Cold Cranking Amps measures required power during cold climate (0 degrees Fahrenheit or -18 degrees Celcius).

The pulse duration is called the "pulse length", and is measured in micro-seconds (one micro-second is one-millionth of a second). The pulse length is usually called the PULSE WIDTH in radar systems.
