LED driver low power by switching mode

When it is applied to the battery. How to make it light long time? or We can use battery longer than usual. This is an issue that we needs. When it is saving, If applied to the other supply, would make saving for sure. Figure 1 as application circuit by source is a voltage of […]


Inverter 12V to 220V 100W by Transistor

This circuit power Inverter 100W, it easy and good ideas. When use the electric appliances that want 220V AC 50HZ, which have small-sized about 100Watt not exceed. By when you apply outside home, as a result have to have Mini power inverter about 100Watt, perform modify from work electricity forces of battery 12V give tall […]
