Title: Charging device of capacitor
Inventor: KOGANEZAWA TAKEHISA
IPC: H02M3/28
Filed: 2007-04-18
Abstract: <P>PROBLEM TO BE SOLVED: To surely prevent the eccentric magnetization of a transformer even if there is a difference between on-times at each half cycle of an inverter, in a charging system for charging a capacitor until its voltage reaches a charging target voltage by using an LC resonance current at each half cycle via the transformer by an output at each half cycle of the inverter.  <P>SOLUTION: An on-time operation circuit 11 outputs a pulse having a width which corresponds to the on-time of an inverter switch according to the charging target voltage of the capacitor. A multiplying circuit 13 obtains an amount of positive or negative magnetic flux generated at the transformer according to the on-time by multiplying the on-time by a DC voltage of the inverter. An adder-subtractor 14 obtains a difference by adding and subtracting the amount of the positive or negative magnetic flux. A zero-comparison circuit 15 determines either positive polarity or negative polarity for an amount of the magnetic flux with a zero as a border. A state change permission circuit 16 latches a determination result of the zero comparison circuit. An on-switch selection circuit 17 selects the polarity of an on-output of the half cycle of the inverter according to a determination result of the state change permission circuit.  <P>COPYRIGHT: (C)2009,JPO&INPIT
