REBOOST POWER CONVERSION APPARATUS HAVING FLYBACK MODE

摘要

A reboost power conversion apparatus (10) having a flyback mode includes a transformer (108), a primary side switch unit (110), a primary side switch control unit (112), a first unidirectional conduction unit (114), a first electric charge storage unit (116), a second electric charge storage unit (118), a second unidirectional conduction unit (120), a mode change-over switch unit (122) and a mode change-over switch control unit (124). The reboost power conversion apparatus (10) has functions of a reboost power conversion apparatus when the mode change-over switch control unit (124) is configured to turn on the mode change-over switch unit (122). The reboost power conversion apparatus (10) has functions of a flyback power conversion apparatus when the mode change-over switch control unit (124) is configured to turn off the mode change-over switch unit (122).
