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
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
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.
