<p>PROBLEM TO BE SOLVED: To eliminate the risk for non-controlled operation due to the noise in the case where a plurality of power converters are operated by introducing a serial transmission system. SOLUTION: Uncontrolled operation is prevented by containing the synchronizing signal of the PWM to a serial transmission information and resetting a PWM generator for every synchronizing signal. Moreover, an accurate control system is realized by transmitting, in synchronization with this synchronizing signal, a gate enable signal, a state information for detection of current and voltage and an information for fault detection.</p> |
