You might want something that shuts off regenerative braking or diverts to an alternative current path e.g. If you start with a fully charged battery and then go straight into regeneration then you'll overcharge/explode your batteries. This is even more of an issue if you are using a boost convertor or chaning coil configuration to increase the regenerative power.Д«) Battery charging. you don't go over the reverse voltage rating of your drive quadrant transistors etc. Two things you have to be careful about though are:ДЄ) You need to make sure all your components are rated for the higher voltages under regenerative braking and e.g. So basically you don't need a boost converter to push current into the battery, having one might help you increase the regenerative power but it is much easier to achieve this by switching the coil configuration if you have a motor with 6/9/12 etc coils.ДЄnother way of thinking about it is if you disconnect any motor which is rotating at high speed without leaving a flyback current path then voltage in motor coil will go very high and arc in order to complete the circuit and discharge the magnetic flux energy in the motor coils (hence why DC motors usually have Schottky diode across poles). If you use regenerative braking mode of a motor controller the controller is only allowing current to go one way, into the battery, the motor coils act like boost inductors and the voltage will naturally rise up to above battery voltage. My main questions are: am I horribly off and on the wrong track? Do I need the boost converter there (some circuits I've seen don't include one)? Would the motor coil by bypassed like I think it will? Anyways the problem I see is that wouldnt current just flow through the loop indicated by the arrow and ignore the motor? I've been googling for answers to BLDC motor regenerative braking and havent really found an answer I can understand, this is what I've managed to piece together from that research.

I know its missing some diodes across the transistors etc but this is more of a concept than anything. L2, T2 and d3 make up the boost converter to increase the voltage to let me recharging the power supply. d1/d2 are the rectifier diodes and C1 is the capacitor to smooth out the voltage signal (not sure if C1 is necessary, please tell me if you happen to know)

L1 is the motor coil, T1 is the transistor/mosfet ill use to switch it on/off. Originally I thought of hooking the terminals of the coils on the motor up to rectifiers but I think this would effectively give me a short. I've had ideas (mostly on paper, circuit diagrams as such) but don't have the things to test them right now or they seem to be flawed.

Correct me if I'm wrong but I believe they are different (the regenerative braking of a brushed motor from my understanding uses the PWM switching as part of a boost converter, to be used as a generator I believe it would have to be spun faster than the power supply would make it spin in order to generate a voltage high enough to recharge it.

My question is with regards to a BLDC motor I plan to use and how I could implement both regenerative braking and the ability to use it as a full on generator to charge the power supply. Hi, I'm new here but have lurked around for answers before.
