When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Here is a simple 12 volts DC to AC inverter circuit. This 120V AC power source is built with a simple 120V:24V or 110V:24V center-tapped control transformer and four additional component. This circuit ...

As the number of Power Over Ethernet (PoE) powered device (PD) applications grows, market pressures are driving designers to lower the cost and complexity of the DC-DC converters that power them, ...

This file type includes high-resolution graphics and schematics when applicable. Low-power applications such as e-meters (electricity or energy meters) often require a simple ac line-powered supply ...

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...
