    • A complementary Silicon-On-Insulator (SOI) Lateral Insulated Gate Rectifier (LIGR) is fabricated in a monocrystalline silicon layer provided on a major surface of a substantially insulating substrate. The monocrystalline silicon layer includes a number of adjacent, doped coplanar layer portions, with the complementary SOI LIGR device being formed of adjacent, contacting layer portions forming two complementary LIGR elements with a common source region. The common source region, as well as both of the drain regions of the device, are composed of regions of both the first and second conductivity types. In this manner, a simple, easily fabricated, balanced, high performance complementary LIGR structure is obtained in which undesired substrate currents are substantially eliminated.
    • 互补的绝缘体上硅绝缘体(SOI)侧绝缘栅极整流器(LIGR)被制造在设置在基本上绝缘的衬底的主表面上的单晶硅层中。 单晶硅层包括多个相邻的掺杂共面层部分,其中互补SOI LIGR器件由相邻的接触层部分形成,形成具有公共源极区域的两个互补LIGR元件。 公共源区以及器件的漏极区都由第一和第二导电类型的区域组成。 以这种方式,获得简单,容易制造,平衡,高性能的互补LIGR结构,其中基本上消除了不期望的衬底电流。

    • A current fed high frequency oscillator-inverter ballast circuit includes a parallel resonant tank circuit for driving a pair of series connected discharge lamps via a series ballast capacitor. A regenerative power supply switches on when a fluctuating main DC supply voltage drops below a given level thereby providing a constant level auxiliary DC supply voltage to the oscillator inverter to maintain oscillation and lamp operation. When the main DC supply voltage exceeds said given level, the regenerative power supply switches out. The oscillation frequency is f.sub.2 during operation of the main supply and automatically switches to a frequency f.sub.1 when the regenerative power supply takes over. The frequency shift is automatic during each half cycle of a 60 Hz AC supply and is in a direction so as to maintain lamp current relatively constant. A novel high frequency leakage transformer may be provided to couple the high frequency inverter to the discharge lamp load to provide both a current limiting (ballast) action and automatic control of the lamp heater current to maintain high efficiency operation.
    • 电流馈送的高频振荡器 - 逆变器镇流器电路包括用于通过串联镇流电容器驱动一对串联放电灯的并联谐振回路。 当主DC电源电压波动低于给定值时,再生电源接通,从而向振荡器逆变器提供恒定电平的辅助直流电源电压,以保持振荡和灯的工作。 当主直流电源电压超过给定电平时,再生电源断开。 在主电源运行期间振荡频率为f2,再生电源接管时自动切换到频率f1。 频率偏移在60Hz交流电源的每个半周期内是自动的,并且处于使灯电流相对恒定的方向上。 可以提供一种新颖的高频泄漏变压器来将高频逆变器耦合到放电灯负载,以提供限流(镇流)动作和灯加热器电流的自动控制以保持高效率的操作。
