Designing a high-voltage capacitor charger or power supply up to a thousand volts is not a trivial task. A discrete solution using a general-purpose flyback PWM controller with an optocoupler, ...

Charge pumps represent an established topology for dc-dc converters that generate low-power inverted and doubled replicas of the input voltage. Typical output currents are as high as 150mA. Such ...

As digital still cameras (DSCs) and mobile phone cameras become more popular, users are demanding higher-quality photos under lower-light conditions. The popular Xenon photoflash is excited by high ...

Capacitors are among the simplest of electronic components – in theory – but the practical implementation is becoming more complex, says Christian Merkel. Capacitors are two conducting plates, ...

What is a pre-charge circuit and what role does it play? The fundamental elements of a pre-charge circuit. Some basic best practices and where to find more information. A common challenge in systems ...
