Automatic AC voltage regulator circuit

This AC drill speed controller circuit schematic allows for the control of the drilling speed of a borer or drilling machine. This project is based on the principle that... The AC drill speed controller circuit is designed to modulate the...

This is a single-zone alarm system featuring automatic exit, entry, and siren cut-off timers. It is designed to accommodate various types of normally-closed input devices, including magnetic reed contacts, foil tape, and passive infrared sensors (PIRs). Additionally, it is...

A 0.001 F coupling capacitor connects the output of the first half of a 556 timer to the input of the second half, providing an individual delay that equals the total delay. The 6-foot ground can immediately activate the...

This setup can function as a cost-effective current source with an output accuracy of 1%. However, the voltage offset can activate the current source even when Vqq equals Vin. Modifying the configuration of Figure 1 can resolve the issue...

The voltage to frequency converter (V/FC - VCO) circuit consists of a UJT (uni-junction transistor) oscillator in which the timing charge capacitor C2 is utilized. The voltage to frequency converter circuit operates by converting an input voltage into an output...

The L620x is a monolithic full bridge switching motor driver implemented using the new Multipower-BCD technology. This technology enables the integration of multiple isolated DMOS power transistors along with mixed CMOS/bipolar control circuits. The L620x series includes various versions:...
