POWER SUPPLY DEVICE FOR HIGH FREQUENCY ELECTRICAL POWER AMPLIFICATION CIRCUIT, AND HIGH FREQUENCY ELECTRICAL POWER AMPLIFYING DEVICE

摘要

In the present invention, bi-directional converters (CONV1-CONV4) are each configured from a rectifier element, a commutation element and choke coils (L1-L4). The choke coils (L1-L4) form a transformer configuration in which the choke coils of the plurality of bi-directional converters are magnetically coupled, and the supply/regeneration of the energy handled by the transformer is adjusted by the ON/OFF control of a switching element that is provided in the bi-directional converter and does not have a parasitic diode. With this configuration, a power supply device for a high frequency electrical power amplification circuit and a high frequency electrical power amplifying device are achieved in which an electrical power source voltage of a high frequency amplification circuit is tracked to a high frequency signal envelope and changed.
