Comparison of V2IC control with voltage mode and current mode controls for high frequency (MHz) and very fast response applications [PDF]
, 2012 High switching frequencies (several MHz) allow the integration of low power DC/DC converters. Although, in theory, a high switching frequency would make possible to implement a conventional Voltage Mode control (VMC) or Peak Current Mode control (PCMC ...

Chaos control of voltage mode controlled buck-boost converter
Acta Physica Sinica, 2016 Due to the limitation to the development level of modern science and technology, DC-DC (where DC stands for direct current) converters operating in chaotic state cannot be used to achieve some desired goals yet and the chaotic phenomena occurring in DC-DC converters are almost restrained. For DC-DC converter operating in continuous conduction mode (CCM)

Control of Transient Power during Unintentional Islanding of Microgrids [PDF]
, 2014 In inverter-based microgrids, the paralleled inverters need to work in grid-connected mode and stand-alone mode and to transfer seamlessly between the two modes. In grid-connected mode, the inverters control the amount of power injected into the grid. In
