“…When the DPC strategy of three-phase PWM rectifier is adopted, the instantaneous power estimation should be made [14,[17][18][19]25]. To simplify the complex coordinate transformation, the instantaneous power of DPC system should always be estimated in stationary coordinate system.…”

“…Hereinto, direct power control (DPC) strategy has become one of the hot research topics in recent years, because of its fast dynamic response, simple structure, and high power factor, and so on [8,11,12,14,[16][17][18]. In general station, the control system of PWM rectifier contains more sensors and complex detection device, which not only increases the volume of the system device and improves the system cost, but also reduces the system reliability of three-phase PWM rectifier.…”

“…Moreover, this method establishes the voltage and the current double closed-loop model, according to the AC voltage and instantaneous power to select the output state corresponding to the switch table. In [8], a direct power control using the natural switching surface was proposed; the proposed control considered the output voltage when selecting the switching states. Therefore, the proposed control does not need an outer voltage control loop and can highly improve the dynamic performance of the DC output voltage.…”

“…When combined with the phase plane, it is widely used in Buck converters [18], [19], Boost converters [20], [34], single-phase inverters [21], [22], three-phase PWM inverters [23], single-phase power factor correctors (PFCs) [24], [25] and dual-active-bridge (DAB) converters [26]. The trajectory used in boundary control is called the switching surface (SS).…”

“…A curved SS for a single inverter was studied and the improved boundary control enhanced its dynamic regulation performance both in light load and overload conditions [32]. A novel direct power control (DPC) using the natural SS of a three-phase PWM rectifier was proposed by combining the DPC with boundary control, which can greatly improve the dynamic performance of the DC output voltage [23]. Because the minimum output voltage deviation and the minimum recovery time cannot be obtained simultaneously, novel control laws using energy balancing were proposed to achieve a superior tradeoff between the voltage deviation and recovery time [33].…”
