    • In a reset period, through applying a rectangular pulse (Pya) of positive polarity to an electrode (Y) and applying a CR pulse (Pxa) of negative polarity to an electrode X, a full lighting pulse is applied between the electrodes (X and Y). The application of the voltage is stopped before a CR pulse (Pxc) reaches a final potential, to generate the pulse (Pxa). A full erase pulse (Pxb) made of a CR pulse having a polarity reverse to that of the pulse (Pxa) is applied to the electrode (X). An erase operation reverses the polarity of wall charges accumulated by a full lighting to effectively perform a potential control operation. The potential control pulse (Pxc) is applied to the electrode (X) to generate a discharge, and the state of the wall charges in a discharge cell is controlled by the discharge to generate an optimal amount of wall charges for a subsequent addressing discharge. The final voltage of the pulse (Pxc) is set equal to a voltage (−Vxg) of an address pulse (Pa). Thus, it is possible to generate a plurality of pulses and stabilize an operation of a PDP with a simple constitution.
    • 在复位期间,通过向电极(Y)施加正极性的矩形脉冲(Pya),向电极X施加负极性的CR脉冲(Pxa),在电极(X, Y)。 在CR脉冲(Pxc)达到最终电位之前停止施加电压,以产生脉冲(Pxa)。 将由具有与脉冲(Pxa)相反极性的CR脉冲构成的完全擦除脉冲(Pxb)施加到电极(X)。 擦除操作反转由完全照明积累的壁电荷的极性,以有效地执行电位控制操作。 将电位控制脉冲(Pxc)施加到电极(X)以产生放电,并且通过放电来控制放电单元中的壁电荷的状态,以产生用于随后的寻址放电的最佳量的壁电荷。 将脉冲的最终电压(Pxc)设定为等于寻址脉冲(Pa)的电压(-Vxg)。 因此,可以以简单的结构产生多个脉冲并稳定PDP的操作。

    • A synthetic round pulse generation circuit can output constant currents (i1, i2). By charging a capacitance element (CP) with the constant currents (i1, i2), a ramp pulse (10a) having a rate of voltage change of i1/CP and a ramp pulse (10b) having a rate of voltage change of i2/CP are applied to the capacitance element (CP). A synthetic round pulse (11) consists of the ramp pulse (10a) and the ramp pulse (10b). In the synthetic round pulse (11), the lengths of application time periods (T10a, T10b) are set so that a discharge is started with the ramp pulse (10a). Further, the rate of voltage change (i1/CP) of the ramp pulse (10a) is set to a small value so that the intensity of the discharge at a discharge starting time (t11f) in the application time period (T10a) may be sufficiently weak. When a PDP is driven with the synthetic round pulse, it is thereby possible to reduce an application time of the round waveform.
    • 综合回合脉冲发生电路可以输出恒定电流(i1,i2)。 通过用恒定电流(i1,i2)对电容元件(CP)充电,具有i1 / CP的电压变化率的斜坡脉冲(10a)和具有i2 / CP的电压变化率的斜坡脉冲(10b) CP被施加到电容元件(CP)。 合成回合脉冲(11)由斜坡脉冲(10a)和斜坡脉冲(10b)组成。 在合成回合脉冲(11)中,施加时间段(T10a,T10b)的长度被设定为以斜坡脉冲(10a)开始放电。 此外,斜坡脉冲(10a)的电压变化率(i1 / CP)被设定为较小的值,使得在施加时间段(T10a)中的放电开始时间(t11f)的放电强度可以是 足够弱 当利用合成圆形脉冲驱动PDP时,由此可以减少圆形波形的施加时间。

    • This invention provides a power unit for an automobile including a motor 6 for starting an engine by transmitting a power thereto and generating a power by receiving a power from the engine during rotation thereof, a power converting circuit 5 for transmitting a power to the motor 6, a battery 1, an energy storing source 20 for storing energy, and a DC/DC converter including at least two switching elements 10, 11, charging the energy storing source 20, and recovering energy in the energy storing source 20 to the battery 1. Since the switch provided in the DC/DC converter is normally turned on when the motor 6 generates power by receiving a power from the engine and charges the battery 1 through the power converting circuit 5 and the DC/DC converter, generation of heat from the DC/DC converter circuit part can be suppressed greatly.
