A steady-state analysis is performed on a dual-bridge LLC resonant inverter. In each line frequency half-period, the phase-shift between the gating signals of two bridges is varying sinusoidally to create pulsing dc link current for grid connection. With phase-shift variation between the two active bridges, different operating modes with corresponding equivalent circuits are identified. Steady-state...
This paper presents a mathematical model for a novel quantum series resonant inverter. This inverter can operate in six resonant modes. The differential equations derived from its equivalent circuit in all operation modes are generalized. At the same time, using the new control technique, the quantized output level which is inherent in the quantum converter can be completely overcome. Thus the output...
