Title: Re: PWM Post by: sanjayrai55 on May 31, 2020, 10:50:06 AM Advantages and disadvantages of pulse width modulation
PWM stands for pulse width modulation, It is a method used to control the output voltage of the converter by modulating the width of the pulse of the output waveform. Here this article gives information about the advantages and disadvantages of pulse width modulation to know more details about it. Advantages of pulse width modulation : Cheap to make Low power consumption Efficiency up to 90 % A signal can be separated very easily at demodulation and noise can be also separated easily High power handling capacity Can utilize very high frequency Little heat whilst working Noise interference is less Very energy efficient when used to convert the voltage or to his light bulb A system in moderate inefficiency among all three types Synchronization between transmitter and receiver is not required unlike pulse position modulation (PPM) Filter requirement is reduced Amplitude and frequency can be control independently Significance reduction in THD of load current Disadvantages of pulse width modulation : The complexity of the circuit Voltage spikes The system requires a semiconductor device with low turn ON and turn OFF times. Hence they are very expensive Radiofrequency interference Electromagnetic noise Bandwidth should be large to use in communication High switching loss due to the high PWM frequency Instantaneous power of the transmitter is varies Title: Re: PWM Post by: sanjayrai55 on May 31, 2020, 10:52:13 AM https://www.dronetrest.com/t/rc-radio-control-protocols-explained-pwm-ppm-pcm-sbus-ibus-dsmx-dsm2/1357
Title: Re: PWM Post by: Somnath Maji on May 31, 2020, 03:43:06 PM What kind of receiver is this?
Title: Re: PWM Post by: sanjayrai55 on May 31, 2020, 05:32:14 PM Read the article, you will know. Next time do a Google search yourself
Title: Re: PWM Post by: Somnath Maji on May 31, 2020, 10:46:34 PM Is in this receiver may I connect 03 Nos. of 9 grms. Tower Pro servo and 30 amp ESC directly?
Title: Re: PWM Post by: sanjayrai55 on June 01, 2020, 05:41:26 AM Yes, but can't connect ESC direct. ESC is connected to battery, and BEC plug will go in the RX
Title: Re: PWM Post by: Somnath Maji on June 01, 2020, 01:54:11 PM So, this receiver has connecting pins like Avionic RZ6 2.4 Ghz?
Title: Re: PWM Post by: sanjayrai55 on June 01, 2020, 04:04:25 PM I think it's about time you made some effort to find out things yourself. As a beginner, it is understandable that you have lot of questions, but if you don't try yourself, you will never learn! Try first, if you come across a real issue, then ask
Title: Re: PWM Post by: newpg202 on June 01, 2020, 04:12:26 PM Hi,
Mainly two types of recivers. 1. Multiple Output Type (Ex. PWM). 2. Single Output Type (Ex. S-Bus) also called Single Line reciver. There are also hybrid receivers which offer both in single package (Ex. frsky X4R, rcb6i, frsky X8R etc, but individual outputs limited to 4, 6 and 8 channels respectively, where as 16 channels (Frsky) in single line S.Bus). If your application involves a Flight Controller go for a single line receiver, as they are fast and provides maximum number of output channels. |
