Patent ID: 7940539

Claim:
A system for issuing a switching command to a single-phase full boost converter comprising a voltage sensor for detecting a DC voltage (v dc ), a current sensor for detecting an alternating current (i a ), and a switch configured to control the i a , the system comprising: a direct-quadrature (D-Q) control system configured to be coupled to the voltage sensor and the current sensor, and further configured to: apply a phase delay to the alternating current (i a ) detected by the current sensor to generate a delay current (i b ); and generate a control voltage (v con ) based on the alternating current (i a ) detected by the current sensor and the delay current (i b ), the control voltage (v con ) comprising a direct-phase voltage component and a quadrature-phase voltage component; and a first comparator coupled to the D-Q control system and configured to be coupled to the switch and to a waveform reference voltage (v tri ) source, the first comparator further configured to: compare v con to v tri , generate the switching command based on the comparison of v con and v tri , and transmit the switching command to the switch.
