Title: Power unit and hid lamp drive circuit
Inventor: IKEDA SHIGEO
IPC: H05B41/282
Filed: 2002-05-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a power unit which can realize high output of a chopper circuit by lessening resistance loss without being influenced by the ON-resistance of a switching element or the dispersion of the forward voltage of a diode.  <P>SOLUTION: When pulses are outputted alternately from output terminals OUT1 and 2 of a controller CT, switching elements Q1 and Q2 of a step-down chopper circuit CH are turned on alternately, and currents IL1 and IL2, which flow alternately to reactors L1 and L2, rise gradually with a lapse of time interval t. When the power, calculated with a power arithmetic circuit M, reaches a specified value, the pulses from the output terminals OUT1 and 2 of the control circuit CT vanish, the switching elements Q1 and Q2 are turned off, and the currents IL1 and IL2 flowing to the reactors L1 and L2 drop with the lapse of the time interval t from their peak values. At this time, even if there is dispersion in the ON-resistance of the switching element or the forward voltage of the diode, the currents flowing in the switching elements become equal, which can remove the unbalance of the loss of the switching elements and the diode.  <P>COPYRIGHT: (C)2004,JPO
