DSPIC30f2010 PURE SINE INVERTER CIRCUIT WITH CHARGER

-
Image
THE DSP30f2010 INVERTER .  The circuit am sharing today is an inverter circuit which can also charge every inverter/solar battery with a selected charge current. As said earlier, the inverter / circuit runs on a digital signal processing micro-controller made by micro-chip. You can download the datasheet by clicking Here. The inverter has the following functions and protections . 1. Ability to work as inverter or UPS. 2. MOSFET protection system using LM324 3. Better battery charging algorithm 4. Low voltage protection 5. high voltage Protection 6. Works on 12V, 24V, 48V, 96V, 120V 7. Overload protection 8. Over charging protection 9. Over battery protection 10. Load display 11. Cooling fan failure detection and tripping with alarm 12. NTC sensor failure detection and tripping with alarm 13. Over Temperature protection 14.

sinewave inverter circuit SG3524(PWM)

-
Image
A 500W PWM inverter circuit built around IC SG3524 is shown here. SG3524 is an integrated switching regulator circuit that has all essential circuitry required for making a switching regulator in single ended or push-pull mode. The built in circuitries inside the SG3524 include pulse width modulator, oscillator, voltage reference, error amplifier, overload protection circuit, output drivers etc. SG3524 forms the heart of this PWM inverter circuit which can correct its output voltage against the variations in the output load. In a non PWM inverter the change in output load directly affects the output voltage (when output load increases output voltage decreases and vice versa), but in a PWM inverter the output voltage remains constant over a range of output load. CIRCUIT DIAGRAM OF 500W PWM INVERTER. ABOUT THE CIRCUIT. Resistor R2 and capacitor C1 sets the frequency of the ICs internal oscillator. Preset R1 can be used for fine tuning of the oscillator frequency. Pi...

Interfacing 4×4 keypad with LCD using 8051 microcontroller is very important step to enter big project.  So here I have discussed regarding Interfacing4x4 keypad with LCD using 8051 microcontroller. In my previous post, I was discussed on Interfacing LCD with 8051 microcontroller using Mikro c for 8051. Now we can see how easily we interface keypad and send the data to LCD for display using MikroC for 8051.   Project Detail: In this project we use AT 89c51 microcontroller and interface 4×4 keypad at port 0 and LCD at port 2. Interfacing 4x4 keypad with LCD using 8051 microcontroller From this Proteous simulation circuit diagram we can see that four resistors R1,R2,R3,R4 are connected in P0.0,P0.1,P0.2,P0.3. These resistors are work as a pull-up resistor. Because we know for input/output operation of port0 of 8051 microcontroller need pull-up resistor. For more details regarding ports in 8051 read my previous post “Ports in 9051 microcontroller”. Here you see the comp...
