PROBLEM TO BE SOLVED: To provide the title inductance load driving bridge circuit capable of increasing the power supply voltage impressing the inductance load while suppressing the complification of circuit composition. SOLUTION: When the switches H2, L1 of switching bridge 1 are turned off, the current generated by the voltage due to the magnetic energy of a coil 5 runs through a diode D in parallel with the switches H1, L2 to charge a capacitor 3. At this time, the charge of a battery 6 is prohibited by a diode 2 so that a capacitor 3 may be charged with higher voltage than the battery VB to be pressed on the coil 5. That is, the large power driving of the coil 5 can be realized by adding the simple circuit composition of the diode 2 and the capacitor 3. |
