The
LCL-Type series resonant converter has nearly load independent output voltage
under some operating conditions. It behaves as a constant current source (CC)
when operated under resonant frequency. The output voltage of a CC power supply
increases linearly with load resistance. Therefore a constant voltage limit
must be incorporated for its use for applications like arc-welding power
supplies etc .This limit can be done by incorporating clamp diodes. Since no
feedback control is used, the proposed circuit is more reliable and rugged.
