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 (vcon) including direct-phase and quadrature-phase voltage components. The system also includes a comparator configured to compare vconto 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 iavalue, and issue switching commands based on the iaand delayed iavalue 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.
