Latest Patents

Tsuchiya's latest patents include a power conversion apparatus and an air conditioner. The power conversion apparatus features a rectifier circuit that rectifies a first alternating-current voltage, a reactor connected to the rectifier circuit, and a capacitor connected to the output end of the rectifier circuit. An inverter is also included, which generates a second alternating-current voltage through the operations of multiple switching elements. This voltage is applied to a motor that consists of a stator and a rotor. The control unit performs operation controls on the switching elements, allowing the inverter to apply a high-frequency second alternating-current voltage to the motor, generating a regenerative current without impairing the capacitor.

Another notable patent is the motor driving device and air conditioner. This device includes a connection switcher with an electromagnetic contactor connected to a motor winding, which switches the connection condition of the winding. An inverter applies an output voltage as an AC voltage to the winding via the connection switcher. The controller manages the electromagnetic contactor, inverter, and switch, forming a circulating circuit when the switch is set to ON. This innovation enhances the efficiency of motor operations.
