Build a 13.8V, 40A Switching Power Supply
This compact and lightweight workhorse can power your whole station!

In this article I will describe the construction of a switching power supply designed to power a complete ham station, with several radios and accessories. This power supply produces 13.8V regulated to better than 1%, at a continuous load current of up to 40A. It has current limiting, making it appropriate for direct connection to a 12V backup battery. If the current limit potentiometer is turned up, the power supply can deliver up to 60A on an intermittent basis, while maintaining regulation. No minimum load is required. The ripple on the output is about 20mV, and the efficiency is 88%. A cooling fan operates depending on the average current drawn, and a tricolor LED tells you if the voltage is normal, too high or too low. It produces no detectable RF noise at any frequency higher than the main switching frequency of 50kHz (I checked it with an antenna wire looped around the operating power supply, tuning my TS450 from 30kHz to 40MHz). And you get all this in a box that measures just 306 x 150 x 130mm, including all projections, and weighs only 2.8kg!

2007-08-26 09:30:00
This circuit will allow you to operate small devices like laptop computers inside your automobile without an expensive automobile power supply. The circuit takes advantage of the fact that power transformers are linear devices and can be used to step up as well as step down. This is evident by the fact that the supply drives ...

12VDC Fluorescent Lamp Inverter with Mosfet
2007-08-26 09:22:00
It uses a normal 120 to 6V stepdown transformer in reverse to step 12V to about 350V to drive a lamp without the need to warm the filaments. Q1 must be installed on a heat sink. A 240V to 10V transformer will work better then the one in the parts list. The problem is that they ...

Very simple IR detector that controls relay
2007-08-25 16:47:00
The circuit of this Infrared(IR) detector circuit is a simple light relay which triggers when infrared light is applied to phototransistor Q1. This device can be used in control systems. When infrared light is OFF, Q1 transistor and relay K1 are normally closed. When IR diode is transmitting IR light phototransistor Q1 opens and thus relay ...

Power suppy Adjustable 0 - 300V
2007-08-24 15:06:00
This is a simple circuit which can provide an adjustable voltage source of 0 to 330 Volt. The supply is short-ciruit proof. the current is limited to about 100mA. TR1 is a 1:1 mains transformer; it is included for safety. The mains voltage from TR1 is rectified with bridge D1 (1Amp /
above the desired final voltage. Some diodes rectify it, a big filter capacitor smoothes out the DC, and a series pass transistor burns up the excess voltage, so you get the desired output. A simple control circuit drives the pass transistor to hold the output voltage constant. The circuit is simple and uses few parts, but several of these parts are big, heavy, and expensive. And the efficiency is usually only around 50%, often even lower. That produces a lot of heat, which must be removed by big heat sinks and fans.
