What happens to stored energy after a system shuts down? This design shows a way to discharge it only when needed.

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

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 ...

Underlying concepts of switched-capacitor circuits. IoT power management using a resonant switched-capacitor dc-dc converter or ultra-low-power switched-capacitor voltage regulators. For Part 2, go ...

Featuring a highly efficient capacitor-powered motor, a series of ac fans offer up to 130 cfm airflow in a 120-mm housing. The OA109AP-11-1TBXC 115-Vac and OA109AP-22-1TBXC 230-Vac fans measure 120 x ...

[Dr Ali Shirsavar] from Biricha Digital runs us through How to Select the Perfect Output Capacitor for Your Power Supply. Your switching-mode power supply (SMPS) will require an output capacitor both ...
