DC Characteristics of a Series Resonant DC/DC Converter at Variable-Frequency Control Methods

The series resonant DC/DC converter (SRC) operating above its resonant frequency is used as a power source for many industrial applications where different methods for the SRC output power control are applied. The paper presents DC characteristics at variable-frequencies control methods, which allows for determining the control range for various load parameters. With their help, the static and dynamic behaviour of the load while changing the control parameter is discussed.
