inverts polarity of supplied voltages http://www.reconnsworld.com/forum/list.php?16 Sun, 19 May 2013 09:36:30 -0400 Phorum 5.2.9a http://www.reconnsworld.com/forum/read.php?16,365,365#msg-365 http://www.reconnsworld.com/forum/read.php?16,365,365#msg-365
Just woundering if anyone knows of a design to test an inverter to make sure its working

a friend told me to use 3 x 3900 ohms resistors to lower the voltage for the led, would this be ok?

Thanks in advance everyone

The inverter here is just a current inverter designed to change DC Current from your car battery into AC current for use on AC devices such as a Laptop, or, if your the kind of person who needs such a Thing in the car, a toaster.]]> andrew Voltage Inverters Tue, 09 Mar 2010 03:21:11 -0500 http://www.reconnsworld.com/forum/read.php?16,8,8#msg-8 http://www.reconnsworld.com/forum/read.php?16,8,8#msg-8

parts:
U1 NE555 timer IC
R1 1.2k ohm resistor
R2 3.9k ohm resistor
R3 1k ohm resistor
C1 0.05 uF ceramic capacitor
C2, C3 220 uF electrolytic capacitor
D1, D2 1N4002 diode

all resistors are 5 or 10 percent tolerance, 1/4-watt
all capacitors are 10 percent tolerance
this circuit inverts the polarity of the input. output is limited to less that 200mA.]]> andrew Voltage Inverters Wed, 08 Dec 2004 08:45:37 -0500
