   Basic working principle

When switch SW1 is closed, current flows out from the power supply VIN, and the path is: VIN→L1→SW1→GND. At this time, the inductor stores magnetic energy (the current gradually increases), and the capacitor C2 supplies power to the load (maintaining the VOUT voltage).

When SW1 is turned off, the current in the inductor cannot change suddenly. In order to maintain the current size, an induced electromotive force (polarity is negative on the left and positive on the right) is generated at both ends of the inductor. The inductor voltage is superimposed in series with the power supply voltage, charging the capacitor C2 through the diode D1, and supplying power to the load at the same time. At this time, the VOUT voltage is raised to a level higher than VIN.

2. Key parameters of circuit design

2.1 Selection and calculation of inductor

In the BOOST boost circuit, the selection of inductor is crucial to the circuit working mode, output voltage stability and efficiency. The inductance value and saturation current should be considered in particular: the inductance value determines the current change rate. If it is too high, the startup time will be prolonged. If it is too low, the current may drop to zero quickly when the switch element is turned off and enter the discontinuous conduction mode (DCM); the saturation current of the inductor must be greater than the maximum current (including steady-state peak current and transient spike current) when the circuit is working normally to prevent saturation from causing inductance performance degradation and causing overcurrent and other faults.

The calculation of the inductance value is usually based on the following formula (∆IL is the change in inductor current). The actual value should be 30%-50% larger than the theoretical value to leave enough design margin:

2.2 Selection and calculation of output filter

In the BOOST boost circuit, the output filter plays a key role in filtering out switching noise and maintaining output voltage stability. The typical output filter consists of an output capacitor and a sensing resistor. The main parameter selection points are as follows: The output capacitor capacity needs to determine the minimum capacity based on the required ripple voltage to suppress voltage fluctuations through sufficient charging and discharging capacity; the lower the equivalent series resistance, the better the filtering effect and the longer the capacitor life, which can effectively reduce the high-frequency component in the ripple voltage; the sensing resistor value needs to be as small as possible to achieve accurate measurement of the output current while reducing power loss and balancing measurement accuracy and energy efficiency.

The calculation formula for the output capacitor is (∆VOUT is the allowable ripple of the output voltage). The actual value should be 30%-50% larger than the theoretical value to leave enough design margin:

3. Working mode

Depending on whether the inductor current is continuous, the BOOST circuit can be divided into the following three working modes:

3.1 CCM continuous conduction mode

The working process is: when the switch is turned on, the diode is reverse biased and cut off, the input power charges the inductor, the inductor current increases linearly, and the load is powered by the output capacitor; when the switch is turned off, the inductor discharges to the load and capacitor through the diode, the inductor current decreases linearly but remains positive, and the output capacitor is charged at the same time, and its voltage conversion relationship is Vout = Vin / (1 – D) (D is the duty cycle, the value range is 0 < D < 1).

The conditions that need to be met are:

3.2 BCM critical conduction mode

Since the inductor current has dropped to zero before the switch tube is turned on, zero current switching (ZCS) can be achieved, effectively reducing switching losses and having certain advantages in improving circuit efficiency and reliability.

The conditions that need to be met are:

3.3 DCM discontinuous conduction mode

Its working characteristics are: the inductor current will drop to zero in each switching cycle, which is suitable for light load or low current conditions, and the control characteristics are highly nonlinear.

The conditions that need to be met are:
