Abstract

The invention provides a direct current-alternating current converter, which comprises a first switch, a second switch, a first half-bridge inverter and a second half-bridge inverter, wherein the first switch comprises a first end and a second end; the second switch comprises a first end and a second end; a direct current power supply is received between the first end of the first switch and the first end of the second switch; the first half-bridge inverter comprises a first end, a second end and an output end; the second half-bridge inverter comprises a first end, a second end and an output end; and an alternating current power supply is output between the output end of the first half-bridge inverter and the output end of the second half-bridge inverter.

Description

Technical field [0001] The present invention relates to a converter, and particularly relates to a DC / AC converter. Background technique [0002] In recent years, due to the development of industry and commerce and the progress of society, the products provided are mainly aimed at convenience, reliability, and economic benefits. Therefore, the products currently developed are also more advanced than before and can contribute to society. [0003] When the traditional full-bridge inverter is applied to the non-isolated solar grid-connected system, there are several shortcomings in the PWM modulation method of the full-bridge inverter: If the PWM modulation method of the inverter adopts bipolar switching ( bipolar), there are the shortcomings of large switching loss and poor inverter efficiency; in addition, if the PWM modulation method of the inverter adopts unipolar switching, there is a shortcoming of large leakage current. [0004] It can be seen that the above-mentioned existing m...
