A system and a method for providing a bypass mode operation in single phase ac-ac matrix converter for high intensity discharge (hid) lamps.

摘要

A system and a method for providing a bypass mode operation in single phase AC-AC matrix converter, for providing high voltage to a load, said system comprising: • at least a first set of solid state devices in series with each other and cumulatively, in parallel to said load; • at least a second set of solid state devices in parallel to each other and independently, in series to said load; • at least a gating signal generator adapted to generate gating signals to switch on or to switch off said solid state devices; • at least a first control mechanism adapted to provide logic for: control of gating signal generator in order to provide gating signals in accordance with a first sequence of a pre-determined pattern for entering said bypass mode; and control of gating signal generator in order to provide gating signals in accordance with a second sequence of a pre-determined pattern for exiting said bypass mode; and • at least a second control mechanism adapted to provide logic for control of gating signals based on determination of pre-determined parameters relating to voltage cycles.
