Abstract
The utility model discloses an inverter power supply system, which comprises a DSP control circuit and an inverter circuit. The inverter circuit is used for changing the voltage of an external current and outputting the current to a filter circuit. Then the current is outputted by the filter circuit. The system is characterized in that the external current is outputted to the filter circuit and a sampling circuit simultaneously, wherein the current is sampled in real time by the sampling circuit and sampling results are uploaded to the DSP control circuit to be processed correspondingly by the DSP control circuit. The DSP control circuit is also connected with a drive circuit and the driving process of the drive circuit is realized under the control of SPWM waveform control signals sent out by the DSP control circuit. Both the drive circuit and the DSP control circuit are supplied with power in real time by means of an auxiliary power supply. The inverter circuit is also connected with a buffer circuit. According to the technical scheme of the utility model, a DSP is adopted as the core of the control circuit, so that the data processing capacity of the system is greatly improved. Meanwhile, the design of the system is facilitated and the development cost of the system is lowered simultaneously.
