ABSTRACT:
An energy converter comprising a series-resonant bridge circuit (1) containing at least two thyristors (6, 7), first and second respective diodes (8, 9) connected antiparallel thereto, a high-frequency output transformer (23), and an energy buffer (2). A control circuit (20) is incorporated for generating trigger pulses for the appropriate thyristors in response to the energy of the buffer (2). The energy converter comprises means for ensuring that the diode, antiparallel connected to the last-conducting thyristor, starts to draw current immediately after this thyristor is blocked. The control circuit also generates signals indicative of the presence of current flowing through the diodes (8, 9), which signals control the supply of the trigger pulses to the thyristors (6, 7).
