Title: Controlling a brushless motor
Inventor: Michael T Rajzer
IPC: H02P6/16
Filed: 2022-03-21
Abstract: Commutation control of a brushless DC (BLDC) motor for use with, for example, a power tool in the event of a position sensor failure. Rather than ceasing operation of the motor and indicating a fault or error message to the user, the present invention determines when the next transition should occur based on the time between past hall transitions using a timer. Thus, if one or two position sensors are no longer providing position information to the controller, the controller can determine when the transitions would be changing based on past transitions to continue controlling the motor and prevents the motor from ceasing operation. Signals are received from a position sensor respectively corresponding to transitions between first and second states of the position sensor, wherein the signals are used to indicate a position of the rotor. An amount of time between successive transitions is measured, and a transition time estimate is determined based on the measured amount of time. Commutation of the rotor is controlled using the transition time estimate when the position sensor fails. The method may be used for a power tool, for example motorized ratchet wrenches, drills and drivers.

Title: Bidirectional power semiconductor switch
Inventor: KENAN ASKAN
IPC: H01L25/07
Filed: 2022-04-13
Abstract: A bidirectional power semiconductor switch 1 has a first semiconductor circuit arrangement 11 comprising a first silicon (Si) or silicon carbide (SiC) MOSFET 8 and a parallel connected first IGBT 9, both controlled via a control and driver unit 13. In a turning on process of the bidirectional power semiconductor switch the control and driver unit 13 switches on the first IGBT 9 before switching on the first silicon or silicon-carbide MOSFET 8. In an on-state of the bidirectional power semiconductor switch the control and driver unit 13 may be arranged to maintain both the first silicon or silicon-carbide MOSFET 8 and the first IGBT 9 in an on-state. The parallel arrangement of MOSFET and IGBT allows a very low resistance of the semiconductor circuit arrangement when all devices are active so that power losses are reduced and a special cooling device is not required. A second set of parallel connected MOSFET 12 and IGBT 14 may be connected in series with the first in the first semiconductor circuit arrangement 11. A central conductor path (Fig 2: 29) may be arranged between first and second MOSFETs and first and second IGBTs so that depending on requirements a switching arrangement (Fig. 2: 25) connects one of the three input/output connections (Fig. 2: 26, 27, 28) with the first outer conductor terminal and another with the second outer conductor terminal. Further MOSFET devices (Fig. 2: 17) may be connected in parallel with the first and second MOSFET devices.
