Devices that plug into an AC mains outlet need protection from EMI. A Pi filter, as shown in Figure 1, is often used for this application. Safety standards exist to protect people and equipment should ...

The possibility of creating a frequency-tunable function generator with rectangular and triangular pulses of constant amplitude and electronic synchronous control of equivalent capacitances in the ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

This solar clock was built using a lot of salvaged parts. We find it interesting that [Nereus] combined a ring of storage capacitors with a power cell (translated) to create a hybrid energy storage ...

Chip capacitors are passive integrated circuit (IC) components that store electrical energy. Chip capacitors are simply capacitors manufactured as integrated circuit (IC) devices, also known as chips ...

The top image shows the construction of the ZnS/CuS anode and carbon fiber cathode used in the experiment. The bottom image illustrates the performance of the ZnS/CuS anode/cathode construction ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...
