Circuits & Schematics - High Voltage - 2

EDN You sometimes need a current source for supply voltages as high as 1000 V or more. This current source can be useful for ripple-voltage reduction when the current source’s high-impedance node feeds an electrolytic capacitor to effectively ...

Tom Gross EDN It can be difficult to generate a high-voltage supply from a medium-voltage input, especially if you need a surface-mount design. It is difficult to find surface-mount components with the necessary specs, especially the transformer ...

Gheorghe Plasoianu EDN Designing a high-voltage regulator can pose difficulties associated with component stress, reliability, and costs. This Design Idea offers a solution: a simple unregulated high-voltage supply in series with a low-voltage ...

George Qian, Michael Wu, Analog Devices Design Note 1047 Introduction Isolated flyback converters are used in automotive, industrial, medical and telecom applications where the power supply must be reliable, easy-to-use, high voltage and isolated, ...

Bipin Duggal EDN Piezoelectric tubular positioners that drive manipulators in scanning tunneling microscopes require high-voltage, low-current drive circuits. The circuit in Figure 1 can drive high-resistance, low-capacitance piezoelectric loads at ...

Steven Galecki Electronic Design This circuit automatically attenuates a high voltage by known factors so that it matches the ADC input range for best converter resolution. It's a common challenge to measure voltages that exceed the operating ...

Gheorghe Plasoianu EDN Bench electronic loads are usually rated for voltages less than 100 V, which make it difficult to test high-voltage power supplies. This Design Idea offers an alternative: an inexpensive electronic load rated for 500 V or ...

Introduction Accurately measuring voltages requires minimizing the impact of the instrument connection to the tested circuit. Typical digital voltmeters (DVMs) use 10 M resistor networks to keep loading effects to an inconspicuous level, but even ...

Jesus Rosales, Linear Technology Design Note 545 Introduction Industrial, telecom, medical and automotive applications use a wide variety of regulated voltages to operate effectively, including high voltage and negative rails. When the designer is ...

Sensors, electrostatic traps, and other applications require regulated, high-voltage power supplies that deliver modest amounts of output current. Simplicity, low quiescent current, and compactness are desirable in such supplies. The circuit of ...
