Title:
DRIVE CIRCUIT, MOTOR SYSTEM, AND SWITCHED RELUCTANCE MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/113550
Kind Code:
A1
Abstract:
A drive circuit (1) comprises three arms (10) connected in parallel to a first input terminal (61) and a second input terminal (62) of a power supply (6). Each of the three arms (10) is formed of a series circuit of a first semiconductor switch (S1), a second semiconductor switch (S2), and a diode (D3). The first semiconductor switch (S1) is connected to the first input terminal (61) and has a first regenerative diode (D1). The second semiconductor switch (S2) is connected to the second input terminal (62) and has a second regenerative diode (D2). The diode (D3) is connected between the first semiconductor switch (S1) and the second semiconductor switch (S2).
