| Abstract: | This paper proposes a method based on waveform matching to forecast the zero-crossing point of primary current and increase the output power of high-frequency power supply.However,it has complex computation and slow matching speed using normalized cross-correlation algorithm in waveform matching directly.To improve the speed of image matching,a heuristic hill-climbing searching strategy are presented in this paper,which realized non-ergodic searching and can be used to find the best matching point very quic... |
