Which one of the following load is suitable for load commutation in Si

1.	Which one of the following load is suitable for load commutation in Single phase Half-bridge inverter?(a) R-L load(b) R-L-C overdamped(c) R-L-C underdamped(d) L-loadI have been asked this question by my school teacher while I was bunking the class.Enquiry is from Solid-State Devices in chapter Introduction to Solid-State Devices of Electric Drives
Answer» Correct answer is (c) R-L-C underdamped The EXPLANATION: R-L-C underdamped are leading power FACTOR loads. They do not require any forced commutation TECHNIQUE. Anti-Parallel diodes help in the commutation PROCESS.
