Power electronics technology involved various types of converters. These converters are the application of circuit theory and design techniques, the development of analytical tools toward efficient electronic conversion, control, and conditioning of electric power. The typical undergraduate syllabus will have topics like uncontrolled and controlled rectifiers with R, RL loads; choppers; single-phase and 3-phase inverters; AC voltage controllers, etc. A simulation practice is providing a platform the student to work efficiently in the present and future design industry because due to the advanced development in technology, simulation process is very useful. Here the simulation of converters is presented using PSIM software.
PSIM for Simulation The basic PSIM process in represented in the Figure 1.1. A circuit is represented in PSIM in four blocks: power circuit, control circuit, sensors, and switch controllers. The power circuit consists of switching devices, RLC branches, transformers, and coupled inductors. The control circuit is represented in block diagram. Components in s-domain and z domain, logic components (such as logic gates and flip-flops), and non-linear components (such as multipliers and dividers) are used in the control circuit. Sensors are used to measure power circuit quantities and pass them to the control circuit. Gating signal is then generated from the control circuit and sent back to the power circuit through switch controllers to control switches.
Simulation in Power Electronics 3.1. Diode Characteristics Diodes are active devices constructed to allow current to flow in one direction.
The diode consists of N-type and P-type materials The N-type material is called the cathode and the P-type material is called the anode. There are two types of biasing that can be applied to a diode. For a diode to be forward biased, a power supply is connected with the positive terminal to the P-type material (anode) and the negative terminal to the N-type material (cathode).
The graph below shows the electrical characteristics of a typical diode. When a small voltage is applied to the diode in the forward direction, current flows easily. For a diode to be reversed biased, the power supply leads are set up with the negative terminal attached to the P-type material and the positive terminal attached to the N-type material.
When voltage is applied in the reverse direction through a diode, the diode will have a great resistance to current flow. Different diodes have different characteristics when reverse-biased. Diode Rectifiers Rectifiers are mainly used in power supplies where an AC signal is to be converted to DC. The DC voltage is obtained by passing the rectifier’s output through a filter to remove the ripple (AC components).
There are many possible ways to construct rectifier circuits using diodes. The three basic types of rectifier circuits are: The Half Wave Rectifier The Full Wave Rectifier The Bridge Rectifier In such diode rectifiers, the power flow can be only from the utility ac side to the dc side. A majority of the power electronics applications use such as switching dc power supplies, ac motor drives, dc servo drives and so on use such uncontrolled rectifiers. In this simulation model capacitor filter are use to filtered the ripple content in the output of the rectifier. Advantages & Limitations The following advantages derived when using PSIM in teaching power electronics courses: 1. It provides better visual operation of power electronics converters.
2. Use of software in classroom save the time of the faculty. 3. With its user-friendly interface, its simulation speed, its capability of simulating any type of power converters and control circuits. 4. Students can use this software for their project works. This paper provides a basic approach to deal with the software.
The Only Limitation with this software approach is that the knowledge of computer and depth knowledge of power electronics subject is necessary to identify the truth results. Conclusion This case study provides the visual operations of power electronics converters. As power electronic systems are getting more complex today, the simulation used for education is requiring more features. This approach is time saving and some directions in the development of simulation are discussed in this paper, with the help of present model students can simulate the power electronics circuit with various load & conditions.

Switch Mode Power Supplies MATLAB simulation 1.0 When dealing with switch mode power supply design, we faced a problem in simulating SMPS circuits since most of simulation software is not flexible with simulating circuits which has tapped transformers. We face this problem specially on simulating isolated switch mode converters such as fly-back converter. MATLAB simulink SimPowerSystems block set gives a best solution in simulating switch mode power supplies. From this article I’ll work on design a buck converter works on continuous mode and another in discontinuous mode with calculations and to implement both on MATLAB simulink. Design Problem Design switch mode power supply (a buck converter) for Input voltage 30V, output voltage 20V and with 100µH of storage element for, 1. 100W resistive load, 2. 20W resistive load Find pulse width D for 20 KHz of pulse frequency.
Equations Continuous mode – Equations Discontinuous mode – Equations Case 1: 100W Resistive Load Therefore; Case 2: 100W Resistive Load MATLAB simulation For the simulations, in MATLAB simulink open the SimPowerSystems Block set. First you need to place powergui block on top of your simulation file which found in SimPowerSystems block set. You can select the DC source in Electrical Sources category of the block set and a MOSFET for switching in Power Electronics Category. For the Components Inductor, Capacitor, Resistive load you need to place parallel RLC branch from elements category and you can select the appropriate component from its property window (parameter type drop down menu). Again for the power diode you have to use Power Electronic category.
For the electrical measurements you can use Measurements category in the SimPowerSystems block set and its output can be displayed by using the scope available in Simulink Sinks. For the clock pulse for the MOSFET we can use the pulse generator available in Simulink sources. You can set pulse frequency by changing its period parameter and pulse width by its pulse width parameter. Please note that the current measuring blocks must be set in series to the measurand and voltage measurement must take in parallel to them. I used matrix concatenate block to set all measurements as one output so that I can view them in single scope.
Designed MATLAB model is as below. Continuous Mode Results Discontinuous Mode Results. Hey nice work man but when i am trying the in matlab i am getting the following errors. Warning: You have required continuous-time simulation of a system containing switches or nonlinear elements.
The ode23tb variable-step stiff solver with relative tolerance set to 1e-4 is recommended in order to get best accuracy and simulation performance. For some highly nonlinear models it may be necessary to set the “Solver reset method” parameter to “Robust”.
See “Improving Simulation Performance” chapter in SimPowerSystems documentation for additional information on how to select an appropriate integration method. Invalid port dimension 1 has been specified for input port 7 of ‘simulink1/Matrix Concatenate’. In multidimensional array mode, the sizes of dimensions other than the concatenate dimension must match for all input and output ports.
This requirement is violated along dimension 1 of this input port because the specified size 1 is not the same as the size 2 specified by some other port. Comment by dhananjay 2012 September 24.
