The capacitor auto-discharge module presented in this article is simply a failsafe module that automatically discharges the buffer/filter capacitor in a power supply circuit when its input supply is ...

The residual voltage of a capacitor, rated not over 600V, shall be reduced to 50V or less within _____ after the capacitor is disconnected from the source of supply. Article 460 covers the ...

IEC60335 is the discharge safety standard for all appliances. To protect the user from an electrical hazard, it requires the voltage across the input X capacitor to discharge to less than 34 V within ...

Power Integrations is aiming at larger home appliances needing to meet IEC60335 with an X-capacitor discharger that can empty 6µF in under a second. X-capacitors are part of the EMC input filter of ...

We tend to focus on charge storage in terms of the batteries that power our electronic devices and, increasingly, our cars. But charge storage devices now make an appearance on scales ranging from ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
