10MHz Zero-Voltage-Switched Resonant Inverter for Electrodeless Fluorescent Lamp

A novel QRDCL circuit for zero voltage switched inverter

This paper presents an alternate quasi-resonant dc link (QRDCL) circuit for soft switched inverters which does not require paralleling of a charged capacitor with another charged capacitor or a voltage source. The circuit momentarily pulls down the DC link voltage to zero as commandled by the control circuit to facilitate zero voltage switching (ZVS) of inverter devices. Operation of this circu...

A Class E Resonant Inverter for Use as Electronic Fluorescent Lamp Ballast

Class E Resonant Inverters are theoretically capable of delivering any power to a load and achieve 100% efficiency at any frequency of operation. In practice efficiency in the “high 90's” can be achieved into megahertz frequencies regardless of inverter output powers. The topology also allows the manipulation of output power through sub-optimal operation, with a negligible efficiency penalty. T...

High Frequency Resonant Inverter for Group Dimming Control of Fluorescent Lamp Lighting Systems

Fluorescen t power SUPPlY Dimmer I Electronic bal last I Lamp IAn electronic ballast for fluorescent lamp lighting using a new resonant inverter is proposed. The electronic ballast has high efficiency, light wcight and small sizc bccause the resonant inverter operates at high frequencies with low switching losses. The inverter output power can be continuously controlled by regulating the L-C re...
