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 ...

Jon Munson, Linear Technology Design Note 513 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 ...

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 ...

Alfredo Saab EDN 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. ...

Sajjad Haidar EDN Power supplies with adjustable DC output ranging from 0 V to 30 V or 60 V are on the market. Above 60 V, there are not many. This Design Idea offers a solution. There are many fixed voltage switching mode power supplies (SMPS) ...

Shyam Sunder Tiwari Electronic Design Europe Measuring extremely high dc voltages of 10 kV or more usually requires a suitably equipped high-voltage voltmeter or a digital multimeter and high-voltage divider, along with the proper safety ...
