Summary Solar photovoltaic (SPV) or battery fed multiple load LED lighting applications are gaining importance these days, which require independent voltage regulation and dimming control. Half‐bridge resonant converters are mostly used due to their simple structure. In this paper, a buck‐boost integrated high gain non‐isolated symmetrical half‐bridge series resonant converter is proposed for multiple load LED lighting applications. With the aid of integrated buck‐boost operation, the output voltage can be regulated below and above the nominal input voltage effectively and can produce twice the gain as compared with classical half‐bridge converters. Frequency modulation is implemented for output voltage regulation. Pulse width modulation (PWM) dimming has been adopted for illumination control. The proposed driver results in several advantages such as low cost, compact size, improved efficiency due to soft‐switching, simple control, independent dimming, and effective operation for multiple loads. Thus, the proposed non‐isolated driver configuration is well suited for SPV/battery fed multiple load LED lighting applications. The proposed configuration is tested with single LED load of 22 W and dual‐LED loads of 22 W and 43 W. There is an excellent consensus between the simulation and the experimental outcomes.

“…A diode full bridge rectifier circuit was designed as the initial stage of the plasma power supply. The circuit rectifies the 220 V AC voltage to DC output voltage [31][32][33][34][35][36][37][38][39], which can be adjusted from 0 V to 300 V. A high frequency inverter circuit was designed and located, following by the rectifier DC link capacitor, which receives the DC voltage from the rectifier and converts it to a high frequency pulsating DC output voltage. The full-bridge PWM topology with high switching frequency was developed as an inverter circuit for the designed plasma power supply.…”

High-power plasma power supply is very useful for many industrial and medical applications. Plasma is generated artificially in the laboratory or industry by applying the electric or magnetic field. In this manuscript, we presented the simple 4T analog MOS control high voltage high frequency inverter circuit as a plasma power supply using modulation index technique. The presented plasma power supply operated at 25 kHz frequency and 10 kV peak to peak voltage. It generates a 0 V to 10 kV controllable electric field. The generated electric field is applied and produces plasma, which can be used for many industrial applications. A 10 kV to 5 kW plasma power supply has been practically developed based on the proposed topology and experimentally tested and, additionally, excellent output power conversion efficiency is achieved. From these results, the 4T analog MOS control high voltage high frequency (HVHF) plasma switching power supply is verified.

“…That in turn results in reduced sizes for the passive components, and thus higher power densities, higher loop-gain bandwidths, and faster transient responses. This has led to the investigation of their adoption into different applications conventionally dominated by PWM converters, including DC-DC [18]- [29] and AC-DC conversion [30]- [35]. ammma@elektro.dtu.dk; frmsp@elektro.dtu.dk; ynour@elektro.dtu.dk; akn@elektro.dtu.dk).…”
