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.
