Zusammenfassung:PURPOSE:To drive an inductive load at high speed with a false sinusoidal signal by keeping set resistances connected in series with a load at a value sufficiently larger than the impedance value of transistors and diodes. CONSTITUTION:Four transistors Q1, Q2, Q3, Q4 are bridge-connected with each other. Resistances R1, R2 are connected between a pair of terminals of a bridge circuit and both ends of a DC power supply, respectively. Said resistances R1, R2 have been set at a value sufficiently larger than the value of the ON-state resistance of said transistors Q1, Q2, Q3, Q4 and the forward impedance of diodes D1, D2, D3, D4 of the bridge circuit.
