AI Thread Summary
Direct drive in amplifiers and voltage converters refers to a transformerless design that allows for a more straightforward connection between the amplifier and the load. This design minimizes signal loss and distortion, enhancing performance, particularly in audio applications. Direct drive systems typically eliminate the need for transducer tuning, simplifying the setup process. The term is often confused with mechanical applications, but in electronics, it emphasizes efficiency and direct signal transmission. Understanding direct drive is crucial for optimizing amplifier performance in various applications.

When talking about amplifiers or voltage converters, what is meant by direct drive? The only idea I have is that it does not involve a transformer.
 
Engineering news on Phys.org
Can anyone shed some light on the term "direct drive"?

I see it for example here:
http://www.act-us.info/sensordetail.php?ID=7494&cat=&type=
near the bottom

"As the power amplifier is a direct drive, transformerless design, transducer tuning is usally not necessary. "

What is direct drive and how is it done? When I search google, I mostly come across the mechanical description of this, rather than an electronics description.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
