12V to +/- 20V DC Converter Circuit
A DC to DC converter circuit is designed to convert a DC voltage to another DC voltage with different levels. This specific converter transforms a +12 V DC input into a symmetrical output of +/-20 V DC. Such circuits are...
DC-DC regulating converter
Push-pull outputs are utilized in this transformer-coupled DC-DC regulating converter. It is important to note that the oscillator must be configured to operate at twice the desired output frequency, as the SGI 524's internal flip-flop divides the frequency by two...
Single-phase rectifier DC welding power load from road circuit
A single-phase rectifier DC welding power load from the road circuit is presented. The contactor KM utilizes a CJ20-40A model rated for 220V. An adjustment potentiometer RP is employed to ensure proper arcing, while the relay KA2 is designed for...
Q-multiplier filter circuit
This circuit is designed for selective tuning adjustments between two closely spaced audio tones. The frequency is determined by the values of the capacitors and resistors in the feedback circuit connecting the collector and base of transistor Q1. With the...
variable voltage and current power supply
An alternative method for utilizing operational amplifiers (op-amps) to regulate a power supply is illustrated below. The power transformer necessitates an additional winding to provide the op-amps with a bipolar voltage of +/- 8 volts. This negative voltage is also...
Talema 10VA transformer board
All DAC boards include a power supply section. It is sufficient to connect only a power transformer. This board is designed for a toroidal 10VA transformer manufactured by Talema, which features pins for PCB connection and exhibits minimal electromagnetic field...
