ABSTRACT:
A two-phase bang-bang current control synchronizer for synchronizing two current streams which pass within a hysteresis controller. Synchronization occurs by summing a fixed hysteresis threshold voltage from a master chopper and a sawtooth wave voltage corresponding to a synchronization and outputting a summed signal to an integrator controller which integrated the summed signal and outputs an intergrates signal. A synchronization circuit receives the integrated signal and generates a sawtooth waveform corresponding to an average value of the fixed hysteresis threshold voltage. The sawtooth waveform is fed to the slave chopper and synchronizes the master chopper and the slave chopper.
