Title:
INVERTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/219066
Kind Code:
A1
Abstract:
An inverter device (1) comprises first and second input terminals (11, 12), first and second primary coils (T1, T2), switching units (34, 35), a power supply coil (50), and a secondary coil (T3). The switching units alternatingly switch the applied DC voltage state between: a first state in which DC voltage is applied to the first primary coil and DC voltage is not applied to the second primary coil; and a second state in which DC voltage is not applied to the first primary coil and DC voltage is applied to the second primary coil. Provided is an inverter device having high conversion efficiency as a result of the impedance ZT1 of the first primary coil, the impedance ZT2 of the second primary coil, the impedance ZL of the power supply coil, and the impedance ZT3 of the secondary coil satisfying expressions (1), (2), and (3).
