    • PURPOSE: A multi-level inverter control device is provided to supply an effect reducing the whole cost of a device by using a low performance cell control unit. CONSTITUTION: A multi-level inverter control device controls a multi-level inverter and a multi-level inverter includes a plurality of phase inverters. A control device includes a main control unit (10) and a cell control unit (14). The main control unit transmits phase-delayed reference waves (A1-A6) to the phase inverters. The cell control unit is provided to the phase inverters. The main control unit transmits the reference waves to each cell control unit and the cell control unit compares them with a triangle wave (B) to transmit a pulse width (PWM) control signal to an inverter unit (13).

    • PURPOSE: A power supply protection apparatus is provided to supply stable main output voltage by blocking a failure cause, over voltage which is generated in a boost converter circuit. CONSTITUTION: A power supply protection apparatus comprises a sensing unit(110), a protection switching unit(130), and a delay unit(120). The sensing unit senses the output voltage of a boost converter circuit. The protection switching unit blocks the Vcc(Current Current Voltage) voltage of a drive integrated circuit by receiving a sensing voltage which senses the output voltage from the sensing unit. The protection switching unit includes a shunt regulator. The delay unit is arranged between the sensing unit and the protection switching unit. The delay unit delays a sensing voltage which is provided to the protection switching unit. The delay unit prevents the overshoot generated between the sensing unit and the protection switching unit in an initial operation.
    • 目的:提供一种电源保护装置,通过阻止在升压转换器电路中产生的过电压来产生故障原因来提供稳定的主输出电压。 构成:电源保护装置包括感测单元(110),保护切换单元(130)和延迟单元(120)。 感测单元感测升压转换器电路的输出电压。 保护开关单元通过接收感测来自感测单元的输出电压的感测电压来阻止驱动集成电路的Vcc(电流电压)电压。 保护切换单元包括分流调节器。 延迟单元设置在感测单元和保护切换单元之间。 延迟单元延迟提供给保护切换单元的感测电压。 延迟单元防止在初始操作中在感测单元和保护切换单元之间产生的过冲。
