First of all, let me explain what PZEV cars mean. PZEV is a technical term which is abbreviation of Partial Zero Emissions Vehicle. Any car which has 15 years of life warranty with 10,000 Kilometers drive each year, or in other words 150,000 miles warranty and zero evaporative emissions from its fuel handling system can be called a PZEV provided that it meets SULEV tailpipe emission fixed standards.

Voltage regulation means to prevent the voltage from dropping down or rising above a specific value. A 12 volt regulator circuit will provide exactly 12V under load as well as without load. On the other hand, an un-regulated 12V power supply output voltage with drop under while the load will increase and will rise when not under load. For example, an un-regulated 12V power supply can output 14V when not under load and can drop the voltage to 11V when under 1A load and 10V when under 2A load. This rise and drop of voltage in un-regulated power supplies can sometimes burn sensitive electronics equipments. Read the rest of this entry »
7809 is a voltage regulator integrated circuit(IC) which is widely used in electronic circuits. Voltage regulator circuit can be manually built using parts available in the market but it will take a lot of time to assemble those parts on a PCB. Secondly, the cost of those parts is almost equal to the price of 7809 itself so professionals usually prefer to use 7809 IC instead of making a voltage regulator circuit from scratch. Before you start using 7809, you will need to know about the pin structure of IC 7809. Apparently, it looks like a transistor. It has three pins. For a better understanding, I have given an image of 7809 bellow. Please take a look. Read the rest of this entry »
