Matlab Simulink - Design of power supply system for 50kW EV fast charge system with 2 loads
Budget: £20 – £250 GBP
Using the Matlab Simulink program, design a power supply system for a 50kW electric vehicle fast charge system. Parameters below.
The AC supply to the full wave rectifier is 230 V single phase AC at 50Hz. The loads are as follows:
• The output of DC-DC Converter 1 is to be 30V to power the control system.
• The output of DC-DC Converter 2 is to be 500V to charge the batteries of an electric vehicle directly.
Deliverables and Assessment Criteria
The work to produce this circuit has been broken down into the following activities -the requirements for each activity are described below:
Rectifier Design
design and simulate a full wave rectifier. You may assume that:
• The load resistance, R, is 2Ω
• The load inductance, L, is 30mH
• The source resistance, RS, is 1.5mΩ
• The source inductance, LS, is 40μH
DC-DC Converter 1 Design
design a DC-DC converter based to meet the requirements described above for DC-DC Converter 1. Because this circuit will supply the control system you should ensure the output voltage ripple does not exceed 5% of the output voltage.
Your design work should identify the following:
• A DC input voltage based on the output of the rectifier.
• Appropriate values of the inductor L and Capacitor C.
• A suitable switching frequency.
Please provide design calculations where possible, include the results of simulation of the circuit to demonstrate its performance, and a description of any significant consideration for the selection of the components.
DC-DC Converter 2 Design
design a DC-DC converter to meet the requirements described above for DC-DC Converter 2. The output voltage ripple must not exceed 10% of the output voltage.
Your design work should identify the following:
• The type of converter that is required.
• Appropriate component values.
• A suitable switching frequency.
Please provide design calculations where possible, include the results of simulation of the circuit to demonstrate its performance, and a description of any significant consideration for the selection of the components.
Simulation of Entire System
Then integrate the individual models you have created and simulate the performance as a whole.
