A control technique to eliminate irregular current and voltage pulses in resonant DC link power converters

Resonant DC link power conversion circuits can experience irregular current or voltage pulses due to abrupt changes in the voltage or current that excites the resonant link. This paper presents a control technique to eliminate these irregular pulses in both series and parallel resonant link converters without any additional switch or passive component, resulting in pulses with uniform amplitude. This technique is not restricted to any particular modulation strategy and leads naturally to a design methodology. Experimental results are presented
