METHOD FOR PULSE WIDTH MODULATION SYNCHRONIZATION IN A PARALLEL UPS SYSTEM
摘要
<p>A method for pulse width modulated pulse synchronization in a parallel UPS system uses the locally measured critical bus voltage to detect a zero crossing and adjust the PWM pulse to coincide with the zero crossing. No communication between the units is required to perform synchronizaton, and no "master" and "slave" relationship exists to thereby increase the total system reliability.</p>
