Power Electronics Seminar
- Learn more about Power Design
before you build circuits.
These are different types of power circuits, do a design review,
correct the errors and use them. I improve and update some on
Some of the circuits were not corrected after the product was
made, some are concepts which were not completed. So understand
and build. I will be gald if you improve the circuit, the
improved version and your details can be published here.
All power supplies can be modified as chargers - Battery
Charger and Rechargeable Batteries
Benchtop Power Supply
Here is a German Benchtiop or Lab Power Supply. It has a neat
Voltmeter and Ammeter. It is a Smoothly Variable Regulated DC
Power Supply. The Voltage Potentiometer control is below the
On-Off Power Switch. It is most likely a Linear design without
Switching at high frequencies.
The Red+ and Black- are clearly kept
at a distance to prevent strands of wires from sparking. The
Ammeter has a dial that has Yellow and Red at the end, this
means the load is drawing more current, power, amps, watts...It
could be a short circuit! Smoke, Sparks, Smell, Something is
Heating or Burning? It could be a Motor running at full speed
too! - This Panel design is an example of Simplicity and High
Lean how to use LEDs - Using
LEDs with Battery Power
This certainly has Voltage Regulation and variable control but
that is the CV mode or constant voltage. The CC mode or constant
current may be absent. This protects the supply from overload
and short circuit. The 0-20V is the Variable voltage range. The
5/8A may mean 5A Nominal or continuous. 8A Max limit.
