3.3 Testing TIDA-010210 in PFC Operation

In this test condition, the system is configured to operate in an close-loop control mode. The TIDA-10210 design is implementing a current control loop able to synchronize with the emulated grid voltages of the AC source. On the DC link, the DC load is controlling directly the voltage, thus allowing the user to control the converter power by changing the reference current of the d sequence. In this operating condition, efficiency versus power has been measured.
