It improves the power factor of power supply.
It stabilizes the direct current voltage.
It measures the current of main power supply circuit.
It converts the alternating current voltage to direct current voltage.
It is combined with L to improve the power factor of power supply.
It generates three-phase alternating current and operates compressor.
It is combined with DS62 to improve the power factor of power supply.
It eliminates and absorbs the electrical noise.
It eliminates and absorbs the electrical noise.
It detects the current and protects the compressor and IPM.
It absorbs the rush current so not to run into the main power supply
circuit when the electricity is turned on.
It short-circuits the circuit to current-limiting resistor when the
compressor operates.

2. Control by the difference between the room temperature and the set temperature
The frequency is controlled by the difference between the room temperature and the set temperature.
(1) Frequency when the unit starts operation
9-23. Operational frequency control of outdoor unit
1. Outline
The operational frequency is as following:
First, the target operational frequency is set based on the difference between the room temperature and the set temper-
ature.
Second, the target operational frequency is regulated by discharge temperature protection, high pressure protection,
electric current protection and overload protection and also by the maximum/minimum frequency.
Maximum/minimum frequency in each operation mode.
