The invention discloses a transformerless aviation intermediate-frequency static transformation power supply, and relates to the technical field of intermediate-frequency static transformation power supplies, the transformerless aviation intermediate-frequency static transformation power supply comprises a fixed shell, the fixed shell is connected with an inversion mechanism and a four-bridge-arm inversion main circuit, the fixed shell is provided with a heat conduction plate, a memory spring and a heat dissipation plate below a circuit mounting block, and a protective shell is provided with a dry powder extinguisher tank. The four-bridge-arm inversion main circuit comprises a power switch tube and a direct-current power source E. The power switch tube is composed of three bridge arms Ba, Bb and Bc, and the four-bridge-arm inversion main circuit further comprises a fourth bridge arm Bd. According to the transformerless aviation intermediate-frequency static transformation power source, when a ventilator works to dissipate heat, and the temperature is too high, a memory spring deforms, a heat dissipation plate is pushed to rotate and be opened, and the heat dissipation plate rotates to be opened; and when the circuit mounting block is on fire, high-temperature wax melts, dry powder in the dry powder fire extinguisher tank is sprayed out from a spraying hole, so that the interior of the fixing shell is subjected to autonomous fire extinguishing, and the four-bridge-arm inverter main circuit is small in size, convenient to transport, high in efficiency and capable of saving energy.
