Title:
SWITCHING REGULATOR CIRCUIT
Document Type and Number:
Japanese Patent JP3400990
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a switching regulator circuit which can switch large power and prevent break of a main switch.
SOLUTION: The first and second switch circuit SW1, SW2 are connected between a DC power supply 10 and a common output circuit COUT and have transformers 11a, 11b. Main switches 14a, 14b are connected to primary inductances 12a, 12b of the transformers 11a, 11b in series. Reset circuits RS1, RS2 are connected to the primary inductances 12a, 12b of the transformers 11a, 11b in parallel. The main switches 14a, 14b are alternately turned on. Both are controlled so as not to be turned on at the same time. The reset circuits RS1, RS2 reset the transformers 11a, 11b while the main switches 14a, 14b are in an off-state.
