DC to DC converter converts direct input voltage to alternating signal, has resonant circuits for converting alternating signal to further alternating signals for producing direct output voltages

摘要

The converter has a switching stage with elements for converting the input DC voltage into a first AC signal, a first resonant circuit for converting the first AC signal into a second AC signal used to form a first output DC voltage, a second resonant circuit for converting the first AC signal into a third AC signal used to form a second output DC voltage and a control circuit for setting first AC signal frequency ranges. The converter has a switching stage with switching elements (2,3) for converting the input DC voltage (1) into a first AC signal (VAC1), a first resonant circuit (8) for converting the first AC signal into a second AC signal (VAC2) used to form a first output DC voltage (14), a second resonant circuit (16) for converting the first AC signal into a third AC signal (VAC3) used to form a second output DC voltage (21) and a control circuit (24) for setting various frequency ranges for the first AC signal. Independent claims are also included for the following: a supply stage with a DC-DC converter.
