4 arms half-bridge symmetrical converter design

[YSAAD.1]

We want to control a 4 phase variable reluctance machine. For this we need to make (or buy) 4 arms half-bridge symmetrical converter with the following characteristics:

Max current of the DC bus: 62 A

Max DC bus voltage: 25.2 V

Max PWM frequency: 30 kHz

MOSFET(or IGBT) switch control voltage: 2.5-3.5V

Current sensor for each phase: Yes

Voltage sensor for each phase: No

Voltage sensor for DC bus: Yes

Max weight expected: 40 g

Where I can find this kind of converter? Or, anyone has an example design of a similaire converter?

Thanks for your help,

Sincerely,

[Cristiana SCARAMEL]

Hello @YSAAD.1​ and welcome to the ST Community.

On our website you can find the offers of ST devices to realize an Asymmetrical Half-Bridge PWM Drive

Pointing the mouse on each part of the block diagram, will be displayed the device options to realize it.

You can design your application starting from that.

Once you have selected the devices for your project, if you need support for their use you can come back with more detailed questions.

Good luck :four_leaf_clover:
