Active bridge circuit for exciting bipolar current to produce periodic, modulated magnetic field that is utilized for treatment in traumatology field, has control units and resistors that are connected to ground terminal contact of bridge

摘要

The circuit has two control units (I, III) that are connected to two P-channel MOSFETs (1, 3), and two control units (II, IV) that are connected to two N-channel MOSFETs (2, 4). The control units (III, IV) are connected by a cable (24) of enable signal A, and the control units (I, II) are connected by a cable (25) of enable signal B. A cable (26) provided for input signals is coupled to the control units (II, IV). The control units (II, IV) and resistors (15, 20) are connected to a ground terminal contact (GND) of a bridge (B).
