In my design of 12VDC to 220VAC inverter, This is the schematic part for charging (12v/100Ah) battery. I use avr ATmega 8 micro controller There are three steps for charging (three primary coils) controlled by three relays (R1,R2,R3) And I have two feed back signals , battery voltage and secondary coil (13VAC) which read the input voltage on pri
An UPS is not a voltage regulator. To handle the voltage fluctuations you can use an avr. outlet===>avr---->UPS no UPS is designed for continuous operation as you seems you are looking more for an inverter: outlet----->battery charger----->battery---->inverter---->equipment not sure what you mean by 'clean, pure'
I have used the Fast PWM mode for generating SPWM 16 kHz signal with microcontroller ATMEGA16 wth oscillator frequency 16Mhz (see Atmega16 50Hz sine wave.jpg). Program written in Bascom avr. Our frequency is 50Hz ? time period is 20ms. A half cycle takes 10ms. Recall that the sine table used is only for half a cycle. So, the 32 values m
My hobby is electronic and wish to work inverter DC12V/AC220V 50Hz project in Bascom avr with microcontroller Atmega16/32 16MHZ and need help. For 1st step of project is write code for PWM positiv half cycle sine wave on PWM1A and negative half cycle on PWM1B with 32 samples every cycle. On PWM1A/PWM1B connect 1K resistor IRFZ44N and transformer
As Vdd is connected with 5V, not 12V in your schematic, its ok for logic level operation. Most probably 5V supply to avr and Vdd of IR2110 are common, its good. Your circuit should work. Set duty cycle of PWM correctly. Is your load connected between two common nodes of FETs
Plz help me out
Hi. I need to know the advantages of using Max232 (if any) against simple resistor-transistor level converter for serial port avr programmer. Is max232 able to provide some better level of protection to serial port and avr Mcu compared to to resistor-transistor level converter? Thank you very much
Hi I m n the process of designing a 50hz inverter with feedback and pwm. my question is weather I need feedback loop stabilization using avr as in the case of analog pwm generators like sg3524/25 ICs. Or it is not needed in Ucrocontroller
Hi I m looking to bulid an inverter with 50hz using big transformer (not ferrite) with feedback using the adc of PIC or avr and with three seven segment display of voltage and other functions as well. Please suggest which one is better PIC16f876 or ATmega8(L). Regards
