  • Drive circuit for an electric motor circuit
    Patent number: 11251738
    Abstract: A drive circuit comprises a two port LC inductive network with a source switch operable to switch the network between an ST state and an active state; an inverter and a controller for controlling the On-Off state of the switches of the inverter and the On-OFF state of the source switch, wherein the controller in use operates the switches to provide: a non-drive portion of the PWM period in which the source switch is held open and the top and bottom switches of at least one phase are held closed so that the drive circuit is operating in an ST mode, a drive portion of the PWM period which immediately follows or immediately precedes the non-drive portion in which the source switch is closed and the top and bottom switches are arranged, and in which the controller is configured to employ a PWM pattern in which all of the bottom switches or all of the top switches are moved from the closed state to an open state simultaneously, and further in which the source switch is moved from the open state to the closed state
