Why are HF inverters so expensive?
Abstract—Efficient generation and delivery of high-frequency (HF, 3-30 MHz) power into variable load impedances is difficult, resulting in HF inverter (or power amplifier) systems that are bulky, expensive and inefficient.
Which type of inverter is suitable for HF operation?
In practice, one can utilize any type inverter suitable for HF operation under resistive/inductive loading; amplitude control of the individual inverters can be realized through any suitable means (e.g., supply voltage modulation, phase-shift or outphasing control, pulse-width modulation, etc.).
How do HF inverters work?
Inverter designs at HF generally utilize fundamental-frequency inductive loading of the inverter transistor(s) to achieve the zero-voltage switching transitions necessary for high efficiency.
How do you modulate an inverter output amplitude?
