    • Pulse generating sections (1X, 1Y) convert a DC voltage (Vs) into voltage pulses (Vp), and apply the pulses to the sustain and scan electrodes (X, Y) of a PDP (20). Recovery switching devices (Q3X, Q4X, Q3Y, Q4Y) of power recovery sections (2X, 2Y) are turned on and off under the rising and falling edges of the voltage pulses (Vp), thereby connect recovery inductors (LpX, LpY) to recovery capacitors (CX, CY). Then, the recovery inductors (LpX, LpY) resonate with the panel capacitance (Cp). While the amounts of the resonance currents (ILX, ILY) are small, the inductances of the recovery inductors (LpX, LpY) are high. When the amounts of the resonance currents (ILX, ILY) exceed a threshold value, the inductances of the recovery inductors (LpX, LpY) are reduced.
    • 脉冲发生部分(1 X,1 Y)将直流电压(Vs)转换为电压脉冲(Vp),并将脉冲施加到PDP(20)的维持和扫描电极(X,Y)。 功率恢复部分(2 X,2 Y)的恢复开关器件(Q 3 X,Q 4 X,Q 3 Y,Q 4 Y)在电压脉冲(Vp)的上升和下降沿导通和关断, 从而将恢复电感器(LpX,LpY)连接到恢复电容器(CX,CY)。 然后,恢复电感(LpX,LpY)与面板电容(Cp)谐振。 虽然谐振电流(ILX,ILY)的量很小,但是恢复电感器(LpX,LpY)的电感很高。 当谐振电流(ILX,ILY)的量超过阈值时,恢复电感器(LpX,LpY)的电感减小。

    • An air conditioner employs a refrigerating cycle in which a non-azeotropic mixture of high and low boiling coolants is sealed. The ratio between the high and low boiling coolants of the coolant mixture changes according to a change in the opening of an electric expansion valve 7. A level sensor 19 is arranged in an accumulator 17 that accumulates the liquid phase of the coolant mixture. A value detected by the level sensor is used to calculate the ratio between the high and low boiling coolants actually circulating in the refrigerating cycle. According to the opening of the valve 7 or the ratio between the actual quantities of the high and low boiling coolants, basic operation parameters such as the operation frequency of a compressor 1 are changed. This results in stabilizing and optimizing the operation of the refrigerating cycle even if a cycle temperature or pressure is changed due to a change in the ratio between the high and low boiling coolants of the coolant mixture.
    • 空调采用密封高沸点冷却剂的非共沸混合物的制冷循环。 冷却剂混合物的高沸点冷却剂和低沸点冷却剂之间的比例根据电动膨胀阀7的开度的变化而变化。液位传感器19布置在蓄积器17中,蓄积器17积聚冷却剂混合物的液相。 使用液位传感器检测的值来计算在冷冻循环中实际循环的高沸点冷却剂与低沸点冷却剂之间的比例。 根据阀7的打开或高低沸点冷却剂的实际比例,改变压缩机1的运转频率等基本动作参数。 这导致即使循环温度或压力由于冷却剂混合物的高沸点冷却剂与低沸点冷却剂之间的比率变化而改变而使冷冻循环的操作稳定和优化。
