Abstract

Single-phase full bridge boost converter systems and methods are provided. One system includes a direct-quatrature (D-Q) control system configured to generate a control voltage (v[con]) including direct-phase and quadrature-phase voltage components. The system also includes a comparator configured to compare v[con] to a carrier waveform voltage, generate switching commands based on the comparison, and transmit the switching commands to a current switch. Another system includes a boost converter including multiple switches coupled to a load and an AC voltage source. The switches are configured to provide charging current to the load in response to receiving switching commands. A D-Q control system configured to receive and delay an i[a] value, and issue switching commands based on the i[a] and delayed i[a] value is also included. A method includes performing a D-Q conversion to generate DC current including direct-phase and quadrature-phase current components, and issuing switching commands based on the current components.

Description

technical field [0001] The present invention relates generally to AC-DC power converters, and more particularly to single-phase full-bridge boost converters and methods for charging a load connected to a single-phase AC voltage source. Background technique [0002] In the vector control approach for multiphase converters, time-varying variables (e.g., AC voltage and AC current) are converted to synchronously rotating direct-quadrature (D-Q) reference coordinates to allow the converter system to Constant values ​​work instead of time-varying values. D-Q conversion has been defined for multiphase converter systems (eg, two-phase and three-phase systems), but not for single-phase systems. [0003] Thus, it is desirable to provide a single phase full bridge boost converter system. It would also be desirable to provide a method for charging a load connected to a single-phase AC voltage source. Furthermore, other desirable features and characteristics of the present invention w...
