FEATURES
of a partial resonance power supply with a simple circuit configuration. of the burst mode allows a reduction in standby power consumption. module contains a start-up circuit to ensure stable start-up and to reduce start-up resistance. implementation of all protective functions. These features are described below. Password Vol.02-05-e MR1000 Series P .01 All Rights Reserved Copyright (C) SHINDENGEN ELECTRIC MANUFACTURING CO., LTD. 2002 2-1 Basic Operation Partial resonance power supplies are an effective means of increasing efficiency and reducing noise with a simple circuit configuration. Partial resonance operation requires detection of the secondary zero current (0A) point, and determination of the ON timing for the main switching device. The MR1000 Series incorporates a zero current detection pin (Z/C, pin 1), the negative edge of the voltage in the control coil (wound with opposite polarity to that of the primary coil) being detected in the main transformer and the main switching device switched ON to detect the 0A point of the secondary current.
