In this paper, an LLC resonant dc-dc converter is proposed for high voltage applications. Full bridge inverter, LLC resonant tanks, high voltage transformer and full bridge rectifier are comprised in the proposed converter circuit. In operating frequency of proposing converter, output voltage regulation is achieved by narrow varying. The energy trapped in leakage inductance of the transformer and...
In this paper, a low ripple voltage multiplier (VM) for X-ray power supply is proposed. It consists of three single-phase symmetrical voltage multipliers, which are connected in series at their smoothing columns like string of batteries and are driven by three-phase ac power source. The smoothing column of each voltage multiplier is charged twice every cycle independently by respective oscillating...
A dual-mode input voltage modulation (IVM) control scheme for a three-phase ZCS series resonant (SR) inverter fed three-phase voltage multiplier based DC-DC converter for X-ray power generator is proposed. The three-phase ZCS SR inverter is formed by connecting three single-phase ZCS SR inverters in parallel and delaying the gating signals by 120deg with respect to each other. It operates at constant...
