Abstract
A DC-to-AC power converter having a main DC input and a main single-phase AC output, configured to convert and adapt a DC voltage at the main DC input into a sinusoidal AC voltage of a fundamental frequency at the main AC output and to deliver a rated power at the main AC output to a load includes: a single DC-to-DC converter having as input the main DC input and having a DC output and a tank capacitor being connected to the DC output, two low frequency diodes biased so as to be able to pass current from, respectively to, the DC output to, respectively from, the tank capacitor; and, according to a direct path, a bidirectional voltage-type DC-to-AC converter in cascade with the DC-to-DC converter, the bidirectional voltage-type DC-to-AC converter having a DC input-output connected to the DC output and an AC output-input connected to the main AC output.
