If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

Using voltage data down to the consumer level is essential for grid optimisation and operational flexibility in the new era of intermittent generation and fast-changing user demand. Power grids were ...

For the PDF version of this feature, click here. Hysteretic control, also known as bang-bang control or ripple regulator control, maintains the converter output voltage within the hysteresis band ...

Aiming at the problem of bus voltage control in DC microgrid, a dynamic compensation control strategy based on a residual generator is designed to complete the voltage compensation of DC-DC converter.

Ameren Transmission Co. LLC has energized the first two of four innovative upgrades to ensure its grid remains stable during the utility’s transition to clean energy sources. Known as static ...

See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...
