90Vrms voltage regulator
The circuit is an open-loop RMS voltage regulator designed to deliver 500 watts of power at 90 V RMS, maintaining good regulation within an input voltage range of 110-130 V RMS. When the input voltage is applied, capacitor C1 charges...
5v 1a power supply using lm2575
A power transistor with a voltage drop of 4 volts and a current of 3 amps may dissipate approximately 12 watts of heat, presenting a challenge in series regulators. In contrast, a saturated transistor or MOSFET with a voltage drop...
12-16V-converter
Many devices operate from a car's 12-V electrical system. Some require 12 V, while others need a lower voltage. An automobile battery's output can vary from 12 to 13.8 V under normal circumstances. The load requirements of the device may...
Car Battery 6V or 12V charger circuit
This circuit is capable of automatically charging 6V and 12V batteries quickly and accurately. A key factor in the successful operation of the circuit is the use of a high-quality transformer (T1) that features excellent insulation and short-circuit resistance.
The charging...
MCU power supply wiring portion
High-precision voltage regulator, isolation transformer with the correct wiring, and low-pass filter to enhance the electrical noise immunity of the source portion. The wiring in Figures 20-48 and 20-49 is illustrated in the figures. Chokes (L1, L2) should have an...
0-15 Volt 0-1A Power supply
TR1 provides a constant current to a bank of three zener diodes, thus maintaining a constant voltage independent of supply voltage variations. The resistor Rx is used to sense the PSU output current and to switch off the current to...
SOLAR_POWER_OVERCHARGE_PROTECTION
A voltage regulator is connected across the solar cell to prevent damage to the storage battery due to overcharging. A series diode prevents the array from discharging the battery during hours of darkness. The regulator does not draw power from...
