INVERTER DEVICE
Document Type and Number:
Japanese Patent JP3281021
Kind Code:
B2
Abstract:
PURPOSE: To control discretely a power to be supplied to a plurality of load circuits, while checking a component from becoming large in size and the cost becoming high.
CONSTITUTION: A series circuit of capacitors C11 and C12 for power supply is connected between the opposite ends of a DC power source E, and a series circuit of switching elements S11 and S21 and a series circuit of switching elements S12 and S22 are connected in parallel to the series circuit of the capacitors C11 and C12. Besides one end of a load circuit LD1 is connected to the node of the switching elements S11 and S21 and one end of a load circuit LD2 to the node of the switching elements S12 and S22 respectively, while the other ends of the load circuits LD1 and LD2 are connected to the node of the capacitors C11 and C12 respectively. A control circuit CR1 making first and second switching elements S11, S21, S12, and S22 in separate sets execute ON- operations alternately in a state wherein the respective mutual overlaps of ON-periods of the switching elements S11 and S21, and S12 and S22 are lessened is provided.
