Optimized phase and frequency shifted controller for interleaved ZVS forward power converter |
摘要 |
A power converter controller and a method for controlling a power converter are provided. The power converter includes first and second power transformers, each having first and second primary windings and a secondary winding; and first and second switches that alternately couple primary windings of the first and second power transformers to an input power source. The power converter controller receives a feedback signal, such as a DC power output voltage from the power converter. A voltage controlled oscillator responsive to the feedback signal provides a variable frequency signal. A phase shift controller coupled to the voltage controlled oscillator provides a variable phase shifted signal responsive to the variable frequency signal. Gate drive signals are decoded using the variable frequency signal and variable phase shifted signal for driving first and second switches of the power converter.
