Hi all,
I've got an idea of a simplified buck converter I want to design for the charging of a high amp lead battery (first 1A for testings then 10A and probably 30A), V1 in the schematics below.
Instead of a usual high side switch, I want to use a low side Mosfet (M1), the stepped down voltage is generated with a fixed frequency PWM (uC out) and monitored with 2 ADC inputs of a uC. Since I don't need to have the battery grounded, I want to avoid the unecessary hassle of commuting a high side mosfet.
I would like to know if the topology principle is OK and/or if such design already exists. Any suggestion and critique is welcome.
Thank you in advance.
