• 17:24, 19 February 2024 Philip talk contribs created page Glossary:Decoupling capacitor (Created page with "Variations in the current drawn by one part of a circuit can affect the voltage of the supply, hence affecting another part of the circuit.

• 11:30, 15 February 2024 Philip talk contribs created page MPP inverter (Created page with "Getting the most power out of a PV (or solar) cell or wind turbine isn't straightforward. The output voltage will be maximum if you draw hardly any current, and if you draw as much current as you can the output voltage will drop almost to zero. In either case the power delivered (voltage × current) will be minimal. An MPP or Maximum Power Point controller or inverter will continuously adjust the current drawn in order to maximise the power, for exam...")
