Switching Improves Regulator Efficiency
In this circuit, a full-wave bridge is switched to a full-wave center tap to reduce regulator dissipation. SCR D6 switches between configurations. When D6 is off, the circuit is an FWCT rectifier using D1, D2, and D5. It applies 17...
Build an Experimenters Power Supply
The incoming AC is routed to the primary terminals of a 12.6-volt transformer. The hot side of the AC is connected through a fuse and a single-pole single-throw (SPST) toggle switch. When the switch is in the OFF position, the...
Visible-red-continuous-laser-gun
Q1 and Q2 control the primary windings of transformer T1 using a square wave signal, the frequency of which is determined by the magnetic properties of the transformer. Diodes D1 and D2 serve as base return paths for the feedback...
DIY Circuit Car Battery Charger
This simple circuit consists of a transformer, two diodes, a capacitor, and an ammeter. To charge a battery, connect the positive and negative terminals of the circuit to the corresponding terminals of the battery. When the battery is not charged,...
DCDC single cell flashlight drive circuit diagram
This is a simple and easy-to-build DC-DC driver circuit designed for a single flashlight battery, operating at a parametric voltage of 1.5V. The input current is 90mA, while the light-emitting diode (LED) current is 26mA or higher. The circuit can...
Schematics power supply switching PCB
The switching power supply provides 12 volts at a maximum of 10 amps, utilizing a discrete transistor regulator with an operational amplifier acting as a comparator in the feedback circuit. The schematic does not depict the front panel power-on indicator....
Voltage regulator for projection lamp
The circuit regulates the RMS output voltage across a load, specifically a projection lamp, to 100 volts ±2% for input voltages ranging from 105 to 250 volts AC. This regulation is achieved by indirectly sensing the light output of lamp...
capacitor Explaining a car voltage regulator circuit
The circuit regulates approximately 12V from the car battery down to 5V for use by an Atmel AVR microcontroller. The presence of two capacitors on each side of the linear regulator LM7805 raises questions regarding their purpose. It is suggested...
Switching Circuit
This switching circuit functions as a bank of interlocked mechanical switches. Activating one of the buttons latches its corresponding output while unlatching a previously selected output. A pair of inverters creates a latch for each output. For instance, pressing button...
