This equation shows that to provide the discharge voltage of V disch at some load value and line frequency ω the hold-up capacitor should have the value of C h.. Example 1. With a line voltage V ...
The discharge is made through D3. The average current in R8 is proportional to the capacitance. The voltage that charges the capacitor is the one set in U2 – 5.74V – plus the drops in D1. The voltage ...
3. Touchstone Semiconductor’s TS3002 timer IC is a 555-type device that operates down to 2 V. The Touchstone TS3002 advanced timer IC is optimized around a small timing capacitor (10 pF).It ...
Thoughtful reader Raymond Laagel of Mulhouse, France sent a note with a proof of a Design Idea we published back in 2010. The DI was called Circuit measures capacitance or inductance, and it was by ...
