Lecture 23



HALF-BRIDGE WITH AN R-L LOAD

Assuming that Io is established, the transient has disappeared and load current waveform is symmetrical


HALF-BRIDGE WITH AN R-L LOAD

The s-domain circuit with Q1 switched


HALF-BRIDGE WITH AN R-L LOAD

The s-domain circuit with Q1 switched




HALF-BRIDGE WITH AN R-L LOAD

Example



FULL-WAVE BRIDGE INVERTER

If the load is purely resistive, the feedback diodes are not required.


FULL-WAVE BRIDGE INVERTER

Q1 and Q3 are turned on for the positive half-cycle, Q2 and Q4 for the negative half-cycle. The load voltage value is twice that of the half-bridge, i.e. for ideal switches the full battery voltage appears across the load. The rms load current is twice that of the half-bridge, and the load power is increased by a factor of 4.


FULL-WAVE BRIDGE INVERTER

For analysis of the full-bridge, with an R-L load, equations (4.5)-(4.7) are used with the full battery voltage instead of the centre-tapped value.
