Abstract:
1. A DC-to-DC converter comprising: a first two-pole inverter; a second two-pole inverter connected to said first inverter; a first transformer, said first transformer having a first transformer primary side connected to said first inverter, and said first transformer having a first transformer secondary side; a second transformer, said second transformer having a second transformer primary side connected to said second inverter, and said second transformer having a second transformer secondary side; a first two-pole rectifier connected to said second transformer primary side; a second two-pole rectifier connected to said second transformer secondary side, said second rectifier connected to said first rectifier; a first capacitor connected in parallel to said first two-pole inverter; a second capacitor connected in parallel to said second two-pole inverter; a third capacitor connected in parallel to said first rectifier; and, a control configured to provide a control signal for frequency-synchronous actuation with a ninety-degree phase shift of said first and second two-pole inverters, so that leakage inductances of said first and second transformers together with said capacitors form resonating circuits having resonant frequency substantially twice as great as a clock frequency of said control signal.
