Disturbance simulator checks lines - 10/14/00 EDN-Design
Ideas.....The simple line-disturbance simulator in Figure 1 helps you
check the immunity of line-powered devices to line disturbances and noise;
you can build the device from leftover parts found in a junk drawer......

Dual Monostable Drives Quasiresonant Inverter - 02/17/97 EDN-Design
Ideas.....A zero-voltage-switching (ZVS]controller usually integrates a one-shot
circuit, embodied in a VCO system. An error amplifier monitors the output voltage and
adjusts the VCO's off-time to keep the output value at a constant level. Each on-time
period commences as soon as the primary voltage drops to zero,..... EDN is migrating

Fluorescent Inverter - Build this 20 watt Fluoro Inverter, it drives
two 20-watt tubes or a 40-watt tube!….(electronic circuit added 04/09) |
|
Fluorescent Lamp Inverter - This inverter is very easy to construct,
reliable, and even powerful enough to light up a 15W florescent tube (if you cool your
transistor well). The only hard-to-find piece of this baby is the so-called yellow
inverter transformer. It's a miniature high frequency transformer that has a 25mm x
20mm x 5mm ferrite core, 30 turns of primary, 15 turns of feedback, and 250 turns of
secondary all concentric, wound on plastic frame than wrapped with a 'yellow' adhesive
tape. If you can't find it in your local electronic shops then search for old portable
rechargeble florescent lanterns since they have at least one yellow inverter. Of
course you can wind a handmade transformer which would do the same but it is a very
difficult task when you don't have an original to inspire and it will still need an
appropriate ferrite core. ….(design added 11/08) |

Half Bridge Inverter has Variable Frequency - 10/09/97 EDN-Design
Ideas.....Modern electronic ballasts require added features, such as high-frequency
preheat for filaments, nominal lamp-power control, and light-dimming capability.
Because the output inverter operates in resonant mode, you can control the power or
current of these ballasts simply by varying the switching frequency. To vary the
frequency,..... [Design Idea by Thierry Castagnet, SGS-Thomson Microelectronics,
