Abstract
A power supply system of a transport system includes: a direct-current intermediate circuit; a motor bridge connected to the direct-current intermediate circuit, for supplying power between the direct-current intermediate circuit and the motor that moves the transport appliance; and also an energy storage and a direct-current converter based on indirect power transmission connected between the energy storage and the direct-current intermediate circuit, for controlling the power supply between the energy storage and the direct-current intermediate circuit. The direct-current converter based on indirect power transmission includes: a controllable solid-state switch, for disconnecting the power supply occurring from the energy storage.
