Title: Load driving circuit and load driving method
Inventor: MIZUNO FUMIAKI
IPC: H02P7/03
Filed: 2002-03-01
Abstract: <P>PROBLEM TO BE SOLVED: To perform forward/reverse inversion driving with no trouble by eliminating the generation of 42 V in a load.  <P>SOLUTION: Both ends of the load M are alternately switched by a relay RLY1, while currents Ia, Ib are supplied by the forward/reverse inversion, the high speed switching of semiconductor switches M1, M2 makes PWM drive by using the currents Ia, Ib. In this way, even by using a power source 3 exceeding the rated voltage of the load M, the forward/reverse inversion driving of the load M can be performed with no trouble. Accordingly, as the load M, for instance, in the case of applying a small-sized motor such as in the power window and door lock of an automobile, even if there is difficulty in a technical and cost point in the new development of a motor coil for 42 V, the forward/ reverse inversion driving can be performed with no trouble by not making the load usable in 42 V.  <P>COPYRIGHT: (C)2003,JPO
