A battery backup for the solar-mains hybrid lamp design that supplies a constant light output regardless of available solar ...

Like most other simple circuits, this circuit also has a disadvantage: It is incompatible with some load-power and ac-mains-voltage values. When a fuse burns out, the load stays connected to the ac ...

All circuits need a power source to work. Some products use mains electricity, so they need to be plugged in. Others use batteries, this means they can be taken anywhere but the battery will run ...

Regulations like IEC 1000-3-2 impose limits on the line input current harmonics. Passive solutions to obtain mains harmonic reduction still dominate the consumer and PC market segment. Some inductors ...
