The Current and Voltage Phase Shift Regulation in Resonant Converters With Integration Control

This letter presents an application of the phase controller which allows a regulation of current and voltage phase shift in resonant circuit with nonperiodic voltage waveform. The phase controller has been implemented using the voltage-controlled oscillator generator operating with double resonant frequency, creation of additional auxiliary voltage signal, and phase-locked loop. The results of computer simulations and laboratory experiments show that the proposed phase controller allows a simple and efficient phase shift regulation for all known systems of integration control with a continuous and discontinuous resonant current flow
