Full H Bridge Vs Half H Bridge. A full wave uses 4 diodes but instead of just clipping off half the wave it reverses the polarity of half the wave thereby increasing the efficiency and doubling the frequency. Half an h bridge is just a high current driver stage connecting two of them is what makes the bridge but the name half h bridge has stuck.
For 3 phase drive you need 3 half h bridges for instance so its useful to count them 6 half h bridges can make 3 h bridges or 2 3 phase bridges. Switched mode power supplies smps and welders. This topology is.
In full bridge inverter peak voltage is same as the dc supply voltage.
In half bridge inverter peak voltage is half of the dc supply voltage. This topology is. From 1 to 1 volts this is because is a full bridge as opposed to a half bridge the output voltage is not referenced to ground but rather one of v3 or v4. The circuit diagram of full bridge inverter is as shown in below figure.
