Let’s start our first post with making a clear introduction for Power Electronics applications. Power electronics are one of the main brach of electrical engineering and we are mainly going to write about SMPS type circuits, their calculations and design aspects.
SMPS is also known as switched-mode power supply to control of power for the neccessary application with devices that are turned on and off at decided high switching frequencies.
Controlling of a power is on the base of used components in an application. For SMPS circuits main components are energy storage devices which are known til’ from high school as inductors and capacitors.
Actually, SMPS can be seen in every part of our life if we know where they are used and their applications. For instance, from mobile phone or laptop charger to any device which works with DC needs SMPS to convert it in reliable range and format to use. Moreover, it can also be designed visa verse for any power level with any type of source.
Some important properties of SMPS are high level of efficiency, sensivity, stability to supply any load. It has diffetent applications according to it’s input and output source type. There are 4 main categories which will be desciribed later.
- DC to DC
- AC to DC
- DC to AC
- AC to AC
We will generlly talk about DC to DC converters that also known as DC Choppers.
Even we talked about how SMPS circuits are grorious, like every applications they have some advatages and distavantages.
Advantages of SMPS:
- Higher efficiency (About 70 to 95%)
- Regulated and reliable outputs regardless of variations in input supply voltage
- Small size and lighter
- Flexible technology
- High power density
- Generates EMI
- Complex circuit design
- Expensive compared to linear supplies
For DC Chopper applications, from ideal to real application steps will be applied in this web page.
- Parameter Calculations
- Design Aspects
- Material Selection Criterias
- Simulations at PSIM and/or Simulink softwares
- PCD Design, at EagleCAD and/or Altuim Designer
- Real apllication and simulation comparison
I hope it is an enough introduction for the power electronics part of my personal page. I hope you enjoy, please enter your comments to share with me.
