This chapter introduces the general theory which is common for all circuits implementing rectangular QV cycles. It presents the circuits based on the charge pump first proposed by Roundy et al and provides their detailed analysis. The chapter also introduces the conditioning circuits based on the Bennet's electricity doubler. The goal of the analysis is a derivation of the evolution law of the electrical state of the Bennet's doubler‐based conditioning circuits, considering the parameters of the circuit, the parameters of C t (t) variation and the initial conditions are known. This analysis provides the analytical expressions linking the rate of the energy conversion with the circuit parameters, and defines the restrictions applied on the circuit parameters in order to achieve the desirable mode of the energy conversion. The chapter shows that the electricity is generated both in the steady‐state operation and during the transient process.
