This circuit, while being simple and reliable is unsuitable for applications with power levels above 10 kW due to its high power dissipation. Existing alternatives efficiently recycle the diode reverse recovery energy into the load. However, these suffer from drawbacks such as excessive diode voltage stress or circuit complexity. This paper proposes a reduced rating diode snubber that limits the diode voltage stress over the entire load operating range while keeping the snubber power dissipation to a minimum. A simple circuit model is simulated to evaluate its operation over the entire power supply operating range. It is first experimentally verified with a proof-of-concept 7 kW prototype. Experimental results show a 60 % reduction in power dissipation in addition to a 30 % reduction in diode voltage overshoot when compared with the conventional R-C snubber under nominal operating conditions. Further experimentation with a 100 A, 150 V plasma cutting power supply shows that the output rectifier voltage stress is kept within reasonable limits over a wide load operating range verifying the robustness of the proposed circuit.","PeriodicalId":263412,"journal":{"name":"Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006.

Thiele","doi":"10.1109/APEC.2006.1620531","DOIUrl":"https://doi.org/10.1109/APEC.2006.1620531","url":null,"abstract":"An integrated single-inductor multiple positive/negative output dual-loop DC-DC converter with multiplexed rectifiers for TFT LCD display supply will be presented. The converter operates with a tiny chip-size inductor. Based on the physical behavior of the inductor a very robust power stage will be shown, which can service an unlimited number of positive and negative output channels with a single inductor. All the different voltage levels (positive and negative) will be regulated independently on a cycle by cycle base. There are two different types of regulation loops running in the converter. The control of the individual channels is managed by a state machine (first loop) which takes care of the power stage switching pattern and allows the hysteretic converter to run in a pseudo continuous current mode to guarantee a high power conversion capability. The second loop works as a variable peak current control to minimize the inductor current. It will be demonstrated why running with a controlled peak current also yields in a small output voltage ripple and how the state-machine can help to further control the amount of energy delivered into one output channel. To achieve even lower ripple voltages below 10mV and high accuracy the main output is post-regulated by a tracking current-mode LDO. Finally the whole TPS6512X architecture with the multi-output converter, LDO's and control circuitry will be shown. The converter with 4.5ksqmil chip-size fits in a 16-pin 3/spl times/3 QFN package. Due to the high maximum switching frequency of the device a single, inexpensive and ultra-thin 10/spl mu/H inductor can be used, which offers a very compact and small power supply solution to provide all voltage levels required by small form-factor TFT-LCD panels.","PeriodicalId":263412,"journal":{"name":"Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006.
