MODULAR HIGH POWER BI-DIRECTIONAL HALF BRIDGE BUCK/BOOST CONVERTER ASSEMBLY

The present invention generally relates to a modular high power bi-directional half bridge buck/boost converter assembly and, in particular, to a system for converting power from one form of current (either AC or DC) to a differing level of voltage, either lower (buck) or higher (boost), to output a wave signal based on pulse wave modulation (PWM) switching control by means of an external digital controller and methods of operation. In particular, an inverter-converter system includes at least one half bridge module including a plurality of circuit components, at least one inductor which is connected to the at least one half bridge module and a power supply, and a controller which is configured to receive and send instructions to the at least one half bridge module for converting an input voltage to an output voltage and dynamically tune switching frequencies based on a load of the inverter-converter system.
