摘要（英）：

The invention discloses a solar photovoltaic (PV) elevator control system with bidirectional power flow. The solar PV elevator control system comprises an execution device and a control device. The execution device comprises a permanent magnet synchronous motor (3), a dual PWM (pulse-width modulation) current transformer, a PV module (11), a storage battery (9), a PV controller (10) and a bidirectional DC/DC (direct current) controller (8), wherein, the dual PWM current transformer comprises a motor-side PWM current transformer (4) and a grid-side PWM current transformer (5) which are connected together through a DC bus (7); a branch composed of the PV module (11) and the PV controller (10) is connected with the storage battery (9) in parallel and then is connected to one end of the bidirectional DC/DC controller (8); and the other end of the bidirectional DC/DC controller (8) is connected to the DC bus (7) of the dual PWM current transformer. The solar PV elevator control system has the beneficial effects that feedback and storage of renewable energy are realized; solar PV-generated electricity is fully utilized; and various types of energy are reasonably converted.
