Vehicle A/c System--

                                  vehicle A/c system uses only 2 purpose, 1)Journey is comfortable, and the second thing is 2)Humanity control,
        Many people told when A/c on a car continuous dropping water outside from the vehicle and home made refrigerator don't dropping water outside , this is a simply reason 

                         "Vehicle A/c control the interior humanity,  home made refrigerators don't do that🙂

Vehicle A/c system's have a many component depend on types may be "Manual" or "Automatic
Components are-Compressor,Condenser,Evaporetor, Expansion valve,Low ,Suction, Discharge,and High pressure pipe Lines etc
      Automatic A/c systems have a extra component like Amplifiers

      All component have a specific role

  • compressor
  • condensor
  • expantion valve
  • evaporator unit
  • pipelines
  • fan motor

Compressor

Its working principle is low pressure low tempareture refrigarent convert to high pressure high temperature refrigarent


Condenser 


It's working principle is high pressure high tempareture refrigarent convert to low pressure low tempareture refrigarent


Evaporetor /cooling coil


Cooling coil is enter in evaporator unit and blower fan touch this part to out a cool air in car interrir compartment

Expantion valve

Its working principle is controlling the refrigarent quantityfrom evaporator unit based on interrior humanity; its controoled by a/c pressure switch & ambient tempareture sensor

pipelines 

Those part are connected to some pipelines its have a different name ;compressor to condensor are connected to discharge hose;condenser to expantion valve are connected to high pressor pipelines;expantion vaalve to compressor are connected to low pressor pipe/lequid hose/suction hose 

Fan motor

Its run in two way one is when a/c is on either when /c coolant tempareture is high

Pressure switch

It is component of pressure switch which sense the refrigarent pressure and sense pressure send to the AC Amplifier for compressur magnetic clutch on /off,if this pressure switch damaged or these wiring cut so AC compressur magnetic clutch not work and compressor are totally off

AC Fan motor

AC fan motor that is a part of vehicle AC system when ac fan motor are not working when ac switch on then AC not cooling sufficient these fan motor have a fuse these are basically some time blowing and some time fan motor damaged this why when ac on but interrir tempareture not cool down
  Vehicle refrigarent Name is             r134a   When A/C system leakage need to enter the system is UV oil (that's like a green colour)             Homemade  refrigarent Name is.  r12

Using the SG3525 PWM Controller - Explanation and Example: Circuit Diagram / Schematic of Push-Pull Converter

-
Image
PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a...

N-Channel MOSFET High-Side Drive: When, Why and How?

-
Image
I had previously shown how to drive N-channel MOSFETs in low-side configuration. You can find the tutorial here: http://electel.blogspot.com/2016/12/low-side-mosfet-drive-circuits-and_23.html I’ve been requested to write a tutorial/article regarding high-side MOSFET drive. So, here I’ll talk about N-channel MOSFET high-side drive. Let’s first look at the common low side configuration.  Fig. 1 - N-channel MOSFET configured as low-side switch Now let’s look at a MOSFET configured as a high-side switch. Fig. 2 - N-channel MOSFET configured as high-side switch You can quite easily see the difference between the high-side configuration and the low-side configuration. In the low-side configuration, the load is connected between the drain and +V, while the source is connected to ground. Thus, the gate drive is referenced to ground. So by applying a voltage of >7V (for Power MOSFETs) or >4V (for Logic Level MOSFETs), the MOSFET can be fully turned on. Now let’s talk about the high-si...

Low-Side MOSFET Drive Circuits and Techniques - 7 Practical Circuits

-
Image
In many circuits, it is necessary to use MOSFETs for switching. In many cases, the MOSFET drive signals are generated by microcontrollers. In other cases, they are generated by ICs – PWM controllers, timers or any IC in fact. However, MOSFETs cannot always just be connected to the drive signal and be expected to work properly. Due to the construction of the MOSFET, driving it is not the simplest of tasks, especially for beginners. There are many users who regularly ask for help on MOSFET drive related issues or problems on different blogs, websites and forums. So, here I will show some MOSFET drive techniques/methods for MOSFETs configured as low-side switches. Before I head on to MOSFET drive, let me just tell you what a low-side switch is, in case you don't know. When the MOSFET (that you're using as a switch) sinks current, it is a low-side switch. The load will be between the drain and +V supply. The source will be connected to ground. Gate will be driven with respect to gr...
