Abstract: 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.

Abstract: A flowable food product dispenser is disclosed, The food product dispenser includes a main housing that is designed to be supported on a support surface. The main housing includes an open receiving area that includes a back support wall. An electric drive motor is included within the main housing of the food product dispenser. The main housing receives a storage container assembly that is movable into and out of the open receiving area. The storage container assembly includes a container and a pump. When the storage container assembly is moved into the open receiving area, the drive motor is able to drive the pump to withdraw the flowable food product from the container. A control unit and control panel are operable to allow a user to control the pump to selectively dispense the food product from the dispenser.
