基于dsp的车载逆变器的硬件电路设计

Early traditional inverter technology usually inserted between the inverter and the output level, frequency transformer for electrical isolation and voltage regulation. This technique is also known as low-frequency inverter technology. The inverter technology simple, mature technology, but used to achieve electrical isolation and voltage regulation functions that the traditional frequency transformer low frequency inverter size and weight than the larger. To overcome the shortcomings of traditional low-frequency inverter, this inverter as a high frequency inverter circuit topology of a ring. At the same time more than the traditional analog control of inverter technology, and simulation of control exist, such as in size, temperature drift, etc. shortcomings. In this paper, the function of DSP to achieve the inverter. This paper describes the car inverter circuit topology, for each part of the circuit was introduced and implemented using the DSP hardware to achieve the function of inverter. At the same time to the role of the filter circuit has been studied, using simulation software MATLAB simulation comparison was carried out.
