Now I will say that what is going on E1. apartment blocks of text and drawing attention to the need to be more specific and asked me something like that. He is probably sitting in E1 block. Web. Using the equation for calculating the Period of the **PWM** wave given as; **PWM** Period = [ (PR2) + 1] * 4 * TOSC * (TMR2 Pre-scale Value) The TMR2 Pre-scalar value is selected as 1 and the TOSC is already calculated as 0.02 * 10^-6 seconds. **PWM** period = [22 + 1] * 4 * (0.02 * 10^-6) * 1 This can give a value almost equal to 2 micro-seconds. The **PWM** module has a period and a duty cycle. These are the number of clock cycles used for 1 pulse and the number of those cycles for which the output is high. So, if you want a 16 bit resolution for your **sine** wave, you will need 65536 clock cycles multiplied by a sensible number - lets go with Bob's 32 - so thats 2097152 for a single wavelength. Basically **PWM** is used for dimensioning or trimming the output voltage or power of a particular load as per individual or application requirements. It is a digital way of controlling power and is more effective than analogue or linear methods. There are many examples which illustrates the effective use of **PWM** in controlling the given parameters. Web. Web. Web. For 3-level inverter and **sine** **PWM**, modulation index is evaluated by. m= (V (line-lineRMS)/sqrt (3))*sqrt (2))/ (Vdc/2) Now, when I change the technique to Third Harmonic Injection **PWM** (THIPWM. Pulse-width modulation (**PWM**) is an efficient way to control analog electronics from purely digital FPGA pins. Instead of attempting to regulate the analog voltage, **PWM** rapidly switches on and off the supply current at full power to the analog device. This method gives us precise control over the moving average of energy provided to the consumer. Web. With simple **sine-PWM** you get output voltages with sinusoidal fundamental. For all modulation functions shown below, the voltage output fundamental will be sinusoidal as well. Simply adding a third harmonic ("mod_3rdH") is a very powerful way to improve the inverter perfomance concerning minimum current ripple. Another big advantage of the 3rd. Web. Web.

Generally, the motor end line is exerted with the voltage of a certain form to have **sine** phase voltage to the two ends of the winding. The common generation means includes: **Sine** **PWM** and spece vector **PWM**. Because **PWM** has simple principle and easy realization, it is usually employed as the **PWM** generation means in simple **sine**-wave control. Inverter circuit is the most important application of **PWM** control technology. This paper mainly discusses the unipolar **PWM** ( pulse width modulation ) control mode of single-phase bridge inverter. The **PWM** module has a period and a duty cycle.
