Arrangement for synchronizing the pulse-width-modulated clock signals of several clocked direct voltage converters |
摘要 |
An arrangement for synchronizing the PWM clock signals of several clocked direct voltage converters uses commercially available control circuits for controlling the converters. In the case where the TDA 4714 and TDA 4716 units are used as the control circuits no connection for synchronizing the switching clock signals is provided. The arrangement guarantees the synchronism of the oscillators of all the control circuits and features apparatus by which the phase shift between two switching clocks of two arbitrary direct voltage converters can be chosen to amount to 0 DEG or 180 DEG .
