This is what ClassE amplifiers try to do: ensure that the output transistor never has a simultaneously high voltage across its terminals and a high current going through it. CLASS G AND CLASS H Class G and Class H are quests for improved efficiency over the classic ClassAB amplifier. Both work on the power supply section. The idea is simple. class h amplifier theory As we said above, the Class AB Amplifier is a combination of Classes A and B in that for small power outputs the amplifier operates as a class A amplifier but changes to a class B amplifier for larger current outputs. This action is achieved by prebiasing the two transistors in the amplifiers output stage.

New Class A Amplifier, 600 Watt CW, 10kHz 400 MHz The 600A400 is a solidstate, selfcontained, aircooled, broadband amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Available in a stylish, contemporary cabinet for benchtop use or with cabinet removed for rack mounting. In theory, a class A amp can achieve 50 efficiency with inductive output coupling or 25 with capacitive coupling. Somewhat like a class G or H amp, the class B amp sustains the output most The Class AB Amplifier circuit is a compromise between the Class A and the Class B configurations. This very small diode biasing voltage causes both transistors to slightly conduct even when no input signal is present. An input signal waveform will cause the transistors to operate as normal in their active region thereby eliminating any crossover distortion present in pure Class B amplifier class h amplifier theory Tons of Tones Site explaining non linear distortion stages in Amplifier Models Class D audio amplifiers: theory and design (PDF).
