发明名称 Method for protecting an intermediate circuit condenser in a frequency converter circuit
摘要 The method involves providing two sub modules (22) in a series circuit, which draws electrical power from a power source i.e. battery, via an inductance. A battery voltage is outputted by the power source. Each sub module is provided with a single-phase half bridge (40) on an input side, and a single-phase full bridge (42) on a load side. A fault is detected in one of the sub modules. An electrical power transmission from output terminals (30, 32) of the full bridge of one of the sub modules with the detected fault into one of the sub modules with the detected fault is blocked. Independent claims are also included for the following: (1) a control device (2) a power converter circuit (3) an electric motor.
