LM317T Voltage Regulator with Pass Transistor

www.powerinverters.com 1.877.450.3394 Power Inverter Info The main use of a power inverter is to take battery power (DC power) and convert it to regular power for your electronics/appliaces (AC power). You do this by connecting battery cables from the inverter to your battery and then you are able to plugin your components directly into the power inverter. The usual output voltage might range from 105-115 and sometimes a bit lower if your inverter has a small load on it. Inverters will specify whether they are 12v or 24v. For 24v, you can use multiple 6v or 12v batteries to get to that voltage. For 12v, you can use for instance regular car batteries or deep cycle batteries and connect as many as you want in a 12v setup. The more batteries you have, the more capacity you will have. The capacity of the battery is usually referred to in AH. A regular car battery will have approximately 80-100AH. To protect your power inverter, you could put fuses on your positive cable(s). This can be purchased at almost any car parts store, or a hardware store that sells items related to batteries or cables. A lot of these stores might sell batteries as well, some popular ones being deep cycle, marine, golf cart, 8d, machinery batteries. Some might be 6v, some might be 12v, but you can connect the batteries in series or parallel to add more batteries. Most electronics such as fridges, microwaves, kettles, pots, power tools, lights, fans, compressors, freezers, TVs, sump pumps, etc.. will ...

Sine Wave Inverter (SMPS) Voltage PID Controller using PIC



http://www.youtube.com/watch?v=493WxmETyLk&hl=en

This video shows a DC to AC power inverter that has a regulatet output voltage, and there is no intergrated circuit used. The 50Hz square wave signal gets generated by a 2 transistor oscillator. The 50hz square wave signal then gets amplified with driver transistors, which "drive" the fullbridge that consists 2 TIP122 and 2 TIP127 darlington transistors. So this fullbridge switches the transformer to the power supply and changes it´s polarity - that results AC and this AC is beeing amplified by the transformer. The voltage regulation system consists mainly a voltage divider and a transistor that is "pre biased" and then gets negative voltage from the voltage divider. The NPN transistor then amplifies the difference from these voltages and leads it to the TIP127 PNP transistor which is mainly reliable for the power that gets fed into the transformer. This power inverter does not have that good efficiency. The transistors get pretty hot after some minutes of running the CD radio that I showed. Also the input voltage must be at least 6V higher than the transformer voltage...With a 18V transformer, and 24V input to the power inverter I was able to power a 230V 40W bulb at it´s normal brightness, but the bulb was "flickering" so I don´t know if that came from the power supply or the inverter. This project is rather some kind of "proof of concept" project that I made, but I will share the circuit diagramm soon so you can re built the inverter if you want. The frequency is ...
