Abstract

A power conversion apparatus (1 ) for powering automotive ancillary equipment such as a refrigeration unit (4) that requires a substantially constant voltage and frequency. The apparatus (1 ) includes a variable displacement pump (5) connected to an automobile engine (3), a motor (7) fluidly connected to the pump (5), an alternator (8) coupled to the motor (7) and a controller (6) configured to receive a signal indicative of a speed of the engine (3). In use, the pump (5) is driven by the engine (3) to induce a flow that drives the motor (7), which drives the alternator (8). The controller (6) is configured to control the displacement of the pump (5) based on the speed signal in order to regulate the pressure and/or flow of fluid supplied to the motor (7) from the pump (5) to cause the alternator (8) to supply a predetermined alternating current frequency and voltage to the refrigeration unit (4).
