Hi:
I need a little advice on switching power supplies. I'm looking to build a 500W power supply for an audio amplifier. I'm not too experienced in switching supplies, so I'm doing this as a learning experience.
What is the best topology for this, considering the power and application? From reading general books on power supplies, it seems that, at this power, a full bridge is recommended. From what I've read, the primary currents and voltages at this power level are difficult to deal with in other topologies, like the fly-back, forward/ double-ended forward etc..
I've seen designs on the internet using push-pull for this power level (for audio applications) , but none that use a bridge. From what I've read, dealing with the possible flux imbalance in a push pull can be a big problem, so I'm leaning towards the bridge (via LTC3722) ,however the only bridge circuits I see online are for really high power (in the kWs). I haven't see much else using this topology. Is this a rare topology? What is standard in the audio industry ? (if there is a standard)
What topology do people generally use for this power level? Thanks in advance for any info on this.
