Drag onto the page to add a pulse width modulator.
Formulas are derived for the ensemble average of the pulse power and the RMS pulse width.
Pulse width Modulation device is a circuit which can produce square wave signal with fixed period and adjustable pulse duration ratio (pulse width).
Frequency, current, voltage and pulse width of successive wave and intermittent wave were similar. Frequency, current, voltage and pulse width of sound electric wave changed continuously.
The front panel controls allow the user to set pulse width and frequency independently, or to set frequency and duty cycle, which then sets the pulse width accordingly.
In this method the main part of the pulse width is measured by counter, and the odd of the pulse width is measured by time-voltage conversion method.
The main functions of the pulsed reactor are current limiting and pulse width adjustment.
Design of diode laser driver with strong current and long pulse width
Position control of d. c. motors has been done by means of pulse width modulation.
The time delay and pulse width also depend on propagation distance.
The position of DC motor is controlled by pulse width modulation.
The impact of pulse width, center wavelength and input peak power of the pump pulse on the red-shifted radiation is simulated and analyzed.
The interaction distance relates to the standard deviation, the initial relative phases, the pulse width and the relative amplitude.
This paper studied the three-phase PWM(pulse width modulation) rectifier in dual PWM variable frequency speed regulation system.
User can define rail pressure, pulse width, the amount of volume oil and other parameters by themselves.
Because of built-in PWM circuit (pulse width modulation circuit), dimming range is wider than earlier type products.
Introduction was made to the method of sine pulse width modulation (SPWM) wave generated by table searching, which is based on area equivalence principle.
L297 chip generates pulse phase sequence signals of which the pulse width is adjustable. The signals are the input ones of dual bridge driving circuit and drive the stepper motor after amplification.
The equation for the evolution of the pulse width is obtained, which is analogues to the "energy conservation equation" for a classical particle moving in a potential well.
Capacitive pressure difference sensor is fixed in the center of the tube and connected with the pulse width modulation circuit so that capacitive flow transducer is made up.
A novelty space vector pulse width modulation (SVPWM) technique for the two-phase inverter-fed asynchronous motors system is proposed, which can be widely used in the low or middle power level field.
Taking the effects of space charge and carrier diffusion as well as injected current pulse width into account, an analytic expression of a transit angle of 8 mm Si DDR IMPATT diode is derived.
