Description

Half Bridge resonant SMPS capable of delivering 500W continuous and 700W peak power. It uses unregulated open loop half bridge resonant topology and the output voltage is within +5 and -10% of the nominal voltage when the current draw is varying from 0-100% and the mains supply voltage is 110V or 230V. The main advantage is lower size and cost compared with a similar regulated SMPS and better efficiency compared with the regulated SMPS’s due to the fact that the transformer is driven with almost 50% duty cycle all the time, and the current through the switches has sinusoidal shape, and there are no output inductors. The SMPS features overcurrent protection which limit the output current at about 160% of the maximum power, about 800W. This power supply is suitable for both class AB and class D/T amplifiers, which have the PSRR greater or at least 54dB. Target applications for this power supply unit include the TA3020 based amplifiers and IRS2092 amplifiers for the +-45V +-55V and +-60V versions, two TDA895x based amplifiers for the +-40V version, or two TA2022 amplifiers for the +-32V version. The size of the board is 100x100mm and the maximum height from the PCB is given by the height of capacitors, between 36mm for low profile components up to 50mm for extented height capacitors. The low profile version can be installed in 1RU cases with proper clearance under the PCB. Please mention during order process which height version is required.
