Ultrasound diagnosis apparatus and ultrasound probe

An ultrasound diagnosis apparatus, comprising:

• a transformer including a primary winding and a secondary winding, and configured to drive an ultrasound transducer based on a voltage generated in the secondary winding;
• a first power source configured to cause a potential difference with respect to a reference potential of ground at a first potential that is different from the reference potential;
• a second power source configured to cause a potential difference with respect to the reference potential at a second potential that is different from the reference potential and the first potential;
• a pair of first potential-side switches, each located between one end or another end of the primary winding and the first power source, configured to be capable of turning on and off a connection between both ends of the primary winding and the first power source;
• a pair of second potential-side switches, each located between the one end or the other end of the primary winding and the second power source, configured to be capable of turning on and off a connection between the both ends of the primary winding and the second power source;
• and
• a ground-side switch located between the one end, the other end, or the both ends of the primary winding and the ground, configured to be capable of turning on and off a connection between the primary winding and the ground.

An ultrasound probe, comprising:

• an ultrasound transducer;
• a transformer including a primary winding and a secondary winding, and configured to drive the ultrasound transducer based on a voltage generated in the secondary winding;
• a first power source configured to cause a potential difference with respect to a reference potential of ground at a first potential that is different from the reference potential;
• a second power source configured to cause a potential difference with respect to the reference potential at a second potential that is different from the reference potential and the first potential;
• and
• a switching unit configured to switch a connection path between the primary winding and at least one of the first power source and the second power source to a first connection path that connects the first power source to one end of the primary winding and the second power source to another end of the primary winding, a second connection path that connects the first power source to the other end of the primary winding and the second power source to the one end of the primary winding, or a ground connection path that connects the first power source or the second power source to the ground through the primary winding.
