This chapter deals with three main topologies of DC/DC converters: buck, boost, and buck-boost. After a short presentation of linear conversion drawbacks, fundamentals on switching conversion are explained. The DC/DC converters are analyzed in continuous and discontinuous operating mode and main parameters as gain, critical inductance, and load voltage ripple are calculated. Then, state space averaging is studied and the transfer functions in terms of output voltage versus duty cycle and versus input voltage are obtained.
