A power converter nearly losslessly delivers energy and recovers energy from capacitors (C3, C4) associated with controlled rectifiers (Q3, Q4) in a secondary winding circuit, each controlled rectifier having a parallel uncontrolled rectifier. First and second primary switches (Q1, Q2) in series with first and second primary windings, respectively, are turned on for a fixed duty cycle, each for approximately one half of the switching cycle. Switched transition times are short relative to the on-state and off-state times of the controlled rectifiers. The control inputs to the controlled rectifiers (Q3, Q4) are cross-coupled from opposite secondary transformer windings. 00000 |
