LM317 VARIABLE POWER SUPPLY circuit diagram and instructions

A truly timeless circuit. LM317 is a versatile and highly efficient 1. 2-37V voltage regulator that can provide up to 1.5A of current with a large heat sink. It\'s ideal for just about any application. This was my first workbench power supply and I still use it.

Stepping into firmware

Having had good experience with the Rapman's PIC32-based controller, I decided to stick with that MCU for my new printer. As I mentioned earlier, rather than buy a $1k+ C compiler from Microchip, I bought a much less expensive, full-featured BASIC compiler for the PIC32 {they also offer C and Pascal compilers} and a full development board from Mikroelektronika in Belgrade. Friday night, with the last of the z-axis brackets being printed on my Rapman and the 19 June exhibition in San Francisco co.......

Regulated Current Booster for Power Supply

Regulated Current Booster for Power Supply circuit diagramThis is the regulated current booster designed to increase the DC current of a power supply. Even though the 78xx series of voltage regulators are readily available with diverse current outputs, you could increase the obtainable current output with this circuit. A power transistor is utilized to provide additional current for the load the regulator, preser.......

Build a fully featured Arduino Thermostat

IntroductionIn this post I will attempt to describe the steps I took to build the arduino based thermostat shown in the following videos. The first video was taken when around just half of the coding of the menu system was complete, but gives you a basic run through of the features. This second video shows the completed thermostat with additional features implemented over the holidays, which includes a Total Heat Time counter, and a line graphing feature which shows temperature variations over a.......

LTM4636-1 - 40A ?Module Regulator with Overvoltage/ Overtemperature Protection - Linear Technology

The LTM®4636-1 is a 40A step-down μModule® (power module) switching regulator with stacked inductor as a heat sink for heat dissipation and cooler operation in a small package. The LTM4636-1 detects overtemperature and input/output overvoltage conditions and can trip an upstream power supply or circuit breaker to protect itself and its load.The exposed inductor as a heat sink permits direct contact with airflow from any direction. The LTM4636-1 can deliver 40W (12VIN, 1VOUT, 40A, 200LFM) wi.......

500 Watt Inverter 12VDC to 220VAC

The circuit of 500 Watt Inverter 12VDC to 220VAC is made using a transistor. central component of this inverter circuit is a configuration of 2 pieces of transistors Q1 and Q2 which form a circuit of Flip-Flop. The output of the flip-flop Q1 and Q2 then in severance for each pulse to complement each other using a compiled circuit by Q3 and Q4. Output which complement each other is then given to the driver transistors Q5 and Q6 form the transistor 2SC1061. Power Inverters of this circuit is compo.......

Issues Realting to How to Derate Transistors and Resulting Failures

There are two main pages in this section of the web site; How to derate Transistors by Temperature [Power x Temperature], and Diode Derating [Current x Temperature]. An interrelated page details how to read and Interpret Temperature Derating Curves, which works for diodes or transistors. One of the new pages covers component mounting consideration, as Lead Length vs Thermal Resistance [power dissipation for leaded parts]. This particular topic shows why lead length is an important consideration .......

0-28V 6-8A Power Supply (LM317, 2N3055)

This is an easy to make power supply which has stable, clean and regulator 0-28V 6/8 Amp output voltage. By using two 2N3055 transistors we become more then 2 times the amount of amps then the power supply delivers, making it real though to brake ;). Although you could use this design to deliver 20 amps (with almost no modifications and with a proper transformer and a huge heat sink with a fan), I did not needed such much power. Make sure you mount them on a huge heat sink, as the 2N3055 transis.......
