The Design of DSP Electric Vehicle Charging Power Supply

In today's society, the speed of industrialization is accelerating, and communications between cities are becoming frequent and closer. It is fast and convenient to promote these rapid developments. Traditional transportation usually are fueled by oil which is burning non-renewable, and fuel that cannot be completely burned. Normally, they will be mainly released into the air in the form of carbon dioxide and sulfur dioxide, so fuel trucks bring serious energy and pollution to human’s environment. Therefore, according to the current development situation, this development trend is clearly inconsistent with the laws of human survival, so every country has to develop and improve their green environment. In recent years, some developed countries the electric car to protect the human living environment. The electric car is mainly use the power that stored in the battery stored as a power source to reduce the toxic gas emissions to the air. It can save the oil energy at the same time, so the battery charge is very important. This paper is based on DSP to design an electric vehicle charging power system, charging the battery, mainly for the current development of the status quo, designed clean and environmentally friendly car charging power. From the view of the above problems, this design is based on DSP to design an electric vehicle charging power system, through the DSP event manager to generate PWM control signal to drive thyristor, and then through the power electronics technology, AC-DC conversion DC power supply, and finally to Battery power supply, complete the design. Therefore, this article mainly from the following aspects: (1) DSP is applied in this design. The design of the use of DSP is mainly to the back of the power electronic circuit to provide thyristor drive signal, we know that the 2000 series DSP can provide dead zone PWM to control signal. In Texas Instruments, there are almost 2000 series of DSP are attributed for the MCU series. (2) The application of power electronics in this design. This design is to complete the charge to the battery, to obtain a certain DC power supply. Therefore, there will be using the power electronics technology, from the AC into DC, and lastly to the battery power supply, the entire design contains AC-DC circuit, SCR trigger Circuit, output voltage stabilization circuit.
