This paper presents theory, simulation and experimental verification of a new direct power control (DPC) method in comparison with the conventional switching table based method. In the presented strategy, hysteresis comparators and switching table are replaced by a PWM modulator. The required converter voltage in each sampling period is directly calculated based on measured currents and voltages and system parameters through simple equations. Then, a PWM generator synthesizes the switching pulses for the voltage source converter. Strong theoretical background besides simulation and experimental results has proven the excellent performance and verifies the validity of the proposed power control scheme.
