230V DC PWM (H-Bridge) Motor Driver ? Any Idea ?

Reelf Monsees

We are looking for a driver circuit / application to control motor speed and direction via a full-bridge / H-bridge driver.

The motors a 230V DC, 150W, 0.9A, brushed.

Ideally, the input voltage for the application would be 230V AV (mains). An isolated powersuplly, step down, buck) from the rectified 230V AC (= 325 DC) would

also be possible as an input stage.

Thanks in advance !

Hi Reelf,

Please look at www.ti.com/.../TMDSHVMTRPFCKIT as an example.

Thanks very much. Interesting approach, but unfortunately, total "overkill" for this application.

Hi Reelf,

Sorry, I missed that the motor was brushed.

We do not have motor drivers that operate as such high voltages.

To reach these voltages, a gate driver such as www.ti.com/.../products.html will be needed plus external FETs.
